Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...

If you open up the perennial favourite electronics textbook The Art Of Electronics and turn to the section on transistors, you will see a little cartoon. A transistor is shown as a room in which ...

Back in the late 1960's, I experimented with DTL. That's not a misprint. DTL stands for diode-transistor logic and it was popular in “930-series” logic devices. I used wire-wrap or point-to-point ...

We are all used to the op-amp, as a little black box from which we can derive an astonishingly useful range of circuit functions. But of course within it lurks a transistor circuit on a chip, and ...

Words such as breadboard and prototype have an almost romantic allure in the electrical engineering world. Although the terms are sometimes used interchangeably, they are somewhat different: a ...
