not available for EP0004274of corresponding document: US4204130 Disclosed is an integrated transistor logic circuit (ITL) comprising complementary bipolar transistors. A PNP transistor injects current into the base of an NPN transistor when this current is not steered away. The base of the PNP ...
As we know that a transistor is a combination of two diodes, we have two junctions here. As one junction is between the emitter and base, that is called asEmitter-Base junctionand likewise, the other isCollector-Base junction. Biasingis controlling the operation of the circuit by providing ...

The fundamental op amp circuit (Fig. 13 above) employs an NPN transistor and an op-amp to generate an output proportional to the input's log: VOUT = (- k log10) VIN/RIo The "inverted" circuit, working as a fundamental anti-log amplifier, is depicted in the lower diagram. Typically,...

So, I have already shared the functions of a transistor. These functions are the same for every type. But each type has a different circuit symbol. 7. NPN and PNP BJTs come in two main subtypes, NPN and PNP. NPN has P-type material sandwiched between N-type materials. While PNP has ...
