Yes you are. Getting tired of that stale fish yet?
I stated it won't work.
You did, knowing that most people here don't have the background to realize how baldfacedly you're lying.
In a sense, means in a sense.
Nice tautology. Care to make some sort of point?
Junction transistors are not fabricated by putting two diodes back-to-back. They are fabricated by a process of doping(appropriate to you) and redoping(still appropriate to you) a silicon wafer
Sure they are. But that doesn't prove your first sentence, since semiconductor diodes are constructed that way as well. Making a transistor on a semiconductor in that manner is no different than the process of doping an NP junction layer (a diode) followed by another N layer on top of the exposed P layer (which forms a PN junction, a reversed diode). Voila -- a transistor fabricated from two back-to-back diodes.
You *know* this, which is why you have proudly stated:
"Which, of course, makes my original statement, that a transistor was in a sense two diodes back-to-back, entirely correct."So stop making an ass out of yourself by spending a week attacking *me* for (gasp) agreeing with you on that point. It not only makes you look foolish, it makes you look practically insane.
But hey, don't just take my word for it:
A transistor is formed by placing two diodes back to back in one piece of semiconductor material. This is done by layering N and P material in a sandwich A Brief Review of Transistor TheoryNow, are you going to stop trollishly spewing accusations against me of being a "liar" for stating the truth? Or are you going to keep being an a**hole?Bipolar Junction Transistors: There are two types of BJT -NPN & PNP – These devices are constructed of two diodes back to back Analog and Digital Electronics - ECET- 329
Transistors are sandwiches of three pieces of semiconductor material. A thin slice of n-type or p-type semiconductor is sandwiched between two layers of the opposite type. This gives two junctions rather than the one found in a diode. [one reversed with respect to the other -- Ich.] If the thin slice is n-type the transistor is called a p-n-p transistor, and if the thin slice is p-type it is called a n-p-n transistor. The middle layer is always called the base, and the outer two layers are called the collector and the emitter. We will consider the (more common) n-p-n transistor here, as used in the MadLab circuits. In a n-p-n transistor electrons are the main current carriers (because n-type material predominates). When no voltage is connected to the base then the transistor is equivalent to two diodes connected back to back. LESSON 4 - SEMICONDUCTORS
Now a transistor is merely a "sandwich" of these devices. A PNP transistor is depicted in figure 2 below. Actually it would be two p-layers with a "thin" n-layer in between. What we have here are two p-n diodes back to back. Transistors
A transistor, which lets the current from source to drain to be controlled by a gate, is a pair of diodes connected back to back. Since a transistor is made of two diodes, the next section will first describe what a diode does and how it works. Logic Diagrams to Transistors, December 10, 1993
BJT has two diodes back-to-back. Lecture 24 - PNP transistor
Bipolar Junction Transistors (BJT) - Consists of two diodes connected back-to-back. ICS217 - Digital Electronics
Question: I see a transistor is like two diodes back to back. How can current flow when one diode is always reversed biased? Answer: The short answer is simply that the two diodes are physically close enough together that they influence each other. The long answer is as follows. A junction diode consists of two regions of silicon-an N-type region doped with an impurity that has an extra electron relative to the silicon atom and a P-type region doped with an impurity that lacks an electron relative to silicon. [...] Now we're in a position to consider the transistor, which has three regions of semiconductor (N-P-N or P-N-P) forming two diode junctions back-to-back. The key to the transistor's operation is the fact that the center region (called the base from the days of the point-contact transistor) is very thin, putting the two diode junctions close together. www.chipcenter.com, THE ENGINEER'S TECH-HELP RESOURCE
Now, starting with the bipolar junction transistor (BJT) [...] A BJT comprises two back-to-back diodes, so you can double-check it with an ohmmeter. Troubleshooting at the component level: Understanding component functionality is paramount.
Bipolar junction transistors bipolar junction transistor, a bipolar transistor essentially consists of a pair of PN Junction Diodes that are joined back-to-back The Educational Encyclopedia, Electronic Components
A bipolar junction transistor consists of two back-to-back p-n junctions [a p-n junction is a diode -- Ich.], who share a thin common region with width, wB. Contacts are made to all three regions, the two outer regions called the emitter and collector and the middle region called the base. [...] Since the device consists of two back-to-back diodes, there are depletion regions between the quasi-neutral regions. Chapter 5: Bipolar Junction Transistors
Semiconductor Devices A # 50003: The physical structure of the Bipolar transistor as two back to back diodes. Courses of Aaron Peled, Professor of Electrical Engineering and Photonics
A transistor is two back-to-back diodes, that is alternating layers of either p-type/n-type/p-type (PNP) or n-type/p-type/n-type (NPN). The ‘closeness’ of the two diodes makes it unique, as electrons from one shoot into the other without resistance. Introduction to one of the most important inventions of the 20th Century
Let's cut to the chase and see how fast you try to shift topics again, lest you be nailed down for a change. Is the following an accurate representation of a semiconductor diode, yes or no:
After we've settled *that* question we can move on to the next.
