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 ...

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 ...

It is hard to imagine experimenting with electronics without the ubiquitous solderless breadboard. We are sure you have a few within arm’s reach. The little plastic wonders make it easy to throw ...

Motorola develops a dual-gate transistor in which the two gates can switch on and off independently--a twist the company says could increase performance and reduce power consumption. Michael Kanellos ...

A logic gate is an electronic component (or set of them) that performs a logic operation, in which the binary values 0 and 1 are represented with two different voltage values, as seen in the previous ...

Over the years, readers have often commented that microcontrollers (or more specifically, the Arduino) are overkill for many of the projects they get used in. The admonition that the creator “Should ...
