Scientists in Germany have developed a new silicon-germanium chip that achieves the world’s highest combined sampling rate and bandwidth in a track-and-hold circuit, a key component in ultra-fast signal processing. The advance could improve how data is handled in communication systems, artificial intelligence, and cloud infrastructure.
The work comes from the Heinz Nixdorf Institute at Paderborn University as part of the PACE project. Researchers say the new chip achieves the highest combination of sampling rate and bandwidth ever demonstrated in a track-and-hold circuit, a core component in converting analog signals into digital data.
In simple terms, the chip captures extremely fast-changing signals and converts them into digital form for processing. This function is critical in modern electronics, where systems need to handle massive amounts of data in real time.
The team reports that the system can process more than 500 gigabits per second in a single channel using quadrature amplitude modulation. In multi-channel setups, the data rate could exceed 100 terabits per second, a level relevant for long-distance communication networks.
The new design uses silicon-germanium technology, which allows faster switching speeds while reducing energy consumption. This combination is important for next-generation applications such as 5G and 6G networks, autonomous vehicles, and high-speed sensors.
Silicon-based analog-to-digital converters already operate at extremely high speeds, but improving both bandwidth and sampling rate together has been a technical challenge. The researchers focused on optimizing both parameters to improve overall system performance.
“Transceivers are ‘ambassadors’, so to speak, between analogue and digital. They combine two functions: both sending digital data and receiving data from outside,” explained Maxim Weizel, a research associate involved in the project.
Higher bandwidth allows more data to be transmitted in less time, which directly affects performance in servers, cloud systems, and data centers. For example, network cards with higher bandwidth can significantly improve overall system efficiency.
The team also faced challenges in measuring performance at such high frequencies. Even small errors can introduce phase noise or signal distortion, making accurate testing difficult.
“We worked with extremely high frequencies, which in turn require extremely high precision,” said Weizel. “Even the smallest errors caused disruptive reflections or so-called phase noise.”
To address this, the researchers relied on advanced simulations and high-performance computing resources to validate their design. The chip’s performance was strong enough to push existing measurement systems to their limits.
“Especially in the context of AI, high speed becomes a competitive advantage,” Weizel added, noting that large datasets and real-time communication demand faster processing.
The development also highlights the growing role of advanced semiconductor materials in pushing computing limits. Silicon-germanium combines the manufacturability of silicon with improved electronic performance, making it attractive for next-generation chips. As demand for faster data processing rises, such hybrid materials could play a central role in scaling future communication and computing systems.
The project involved collaboration between several institutions, including RWTH Aachen University, Karlsruhe Institute of Technology, and DESY.
The results are documented in the open-access book “Electronic-Photonic Integrated Systems for Ultrafast Signal Processing.”

It'll be great for the Chinese when the Germans sell them the patents and rights to manufacture. 🙂
They don’t need no steenking patents or rights to manufacture.................
Realistically amazing, but landing something structured, like packets will take a lot more work.
Gonna need much lower energy consumption as ai ramps up and more data centers are created. A step in rigbt direction. The future to be scary good, or scary bad... and i want nothing to do with it! (But if possible ill stick arou d for a few more years and sse how the cards fall for zwhi.e :) )
Was that bzsed on an Eli Wallach quote from one of the Eastwood movies?
I’ve seen the future, I can’t afford it
Tell me the truth sir, someone just bought it
Say Mr. Whispers! Here come the click of dice
Roulette and blackjacks - gonna build us a paradise
Larger than life and twice as ugly
If we have to live there, you’ll have to drug me

Giga is a billion.
Light travels at 186284 miles per second, which is about a foot in a billionth of a second.
So the wavelength of 500 gbps would be 1/500 of a foot, or about 1/40 inch. Wow!
Transceiver = Transmitter + Receiver. So this device is used on the receiver side to extract information at high bandwidth. Nice but now we need a transmitter D/A that can modulate a digital signal on a 200 GHz carrier. I think the unstated value of this may lie in measurement of physical systems, surveillance and instrumentation come to mind.
Ah. Good movie
And keep me drugged. The future is here znd its taking no prisoners
You misspelled steal /S
I’ll tell you what’s interesting: Germany using Germanium.
So I misread the 500 Gbps throughput as the sample rate, which is different. A typical parallel data vector might be 8 bits, which would reduce the sample rate to 62.5 GHz, and would require the bandwidth of the channel to be at least 150 GHz and excellent signal to noise ratio to get to 500Gbps data rate. Still, very impressive.
A bit of a slide from the Silicon Germanium chip to new material that can be used to lower energy and cooling costs of data centers. (If not interested in this just skip.)
This publicly traded U.S. company produces an optical polymer that can help to reduce the voltage and cooling requirements of Data Centers Without rare earths. A Modulators currently need 1. 5 to 3 volts; use of the polymer brings it to .5 to 1 volt, small until you multiply it against the total number in a single data center. They have completed research and are working with chip foundries that are testing the final integration of the the material into their products. It does not require a retooling of existing chip foundries. Here is their website:

"Setting the Record Straight: Why Lightwave Logic (LWLG) is the Real Leader in the Optical Race"
"I’ve seen a lot of misinformation lately around NLM Photonics being “faster” or somehow further ahead, and that really doesn’t hold up when you look at the actual technical record. Both NLM and Lightwave Logic are operating in a similar publicly stated bandwidth range (~110+ GHz), so there is no verified speed advantage on paper for NLM.
What is verifiable is that LWLG, in partnership with Polariton Technologies and ETH Zurich, has powered every major world record in this space—from the 250 GHz EOE link in 2022 to the staggering 1 Terabit (1 THz) milestone in 2025. In fact, these teams explicitly stated that "their testing equipment (the scopes and probes) actually failed before the material did." This indicates real, demonstrated headroom beyond standard measurement limits. Meanwhile, independent academic work has shown alternative material systems plateauing far lower (around ~60 GHz), while Perkinamine-enabled devices pushed dramatically beyond that, reinforcing that this isn’t just marketing—it’s a material-level performance difference.
Where the gap really widens is validation and commercialization readiness. Speed is useless if it breaks in a hot data center. LWLG has passed the industry’s "Gold Standard" (Telcordia 85/85) for 1,000 hours and recently doubled that to 2,000 hours in operating devices—which is the industry gatekeeper for deployment in AI infrastructure. There is no comparable public disclosure from NLM at that level.
This reliability is exactly why Marvell Technology acquired Polariton in April 2026. Structurally, Marvell now owns the "engine" (the device design), but they don’t own the "fuel." It has been officially documented that Polariton utilizes LWLG's proprietary Perkinamine™ to enable these records. Swapping out a certified, 2,000-hour-validated material baked into the design would take years of re-engineering, creating a permanent technical dependency on Lightwave Logic.
The Foundry & Ecosystem Reality There’s also a lot of confusion around foundry relationships. NLM’s announcement regarding foundries is a tape-out and sampling effort - they are using the foundry as a manufacturing partner to validate and demonstrate their designs. That’s normal progress, but it’s still part of the "prove-it" phase. LWLG is operating at a completely different level. Their polymer is already being integrated into live Process Design Kits (PDKs), meaning it is positioned as a standard, designable material option available to customers across those platforms, not just a one-off run. That’s the difference between testing a technology and embedding it into the manufacturing ecosystem for broad adoption.
Finally, LWLG is moving far beyond just data centers. Between their January 2026 move into Quantum Computing with QPICs and the clear alignment with Qualcomm’s 6G roadmap, they are positioning themselves as the "Intel Inside" for the next decade of tech. With their recent move to formalize licensing with top-tier IP counsel Michael Best, the picture is clear: This isn’t about who can throw around bigger numbers—it’s about who is aligning performance, power, reliability, and manufacturability into something that can actually scale. Right now, LWLG appears significantly further along that path, while NLM is still working through earlier-stage validation.
