Thus the three basic bipolar transistor circuit configurations have equivalents ... If you’ve ever used a varicap diode, the capacitance between the two sides of this variable-width zone is ...

When looking across the discrete components in your electronic armory, it is easy to overlook the humble diode. After all ... you’d find in tunnel, Gunn, varicap, Zener, and avalanche diodes ...

In essence, the four-layer diode was the first integrated circuit since it did the work of two transistors, two resistors, and a diode -- all in a single crystal. Unfortunately, they were so ...
