Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

ThermalTrak integrates power output transistors with thermal bias diode. One of the major design concerns in the output section of a typical class AB audio amplifier is output bias and stability over ...

Reading an article about the first transistorized Hi-Fi amplifier, [Netzener] got the itch to make one. But what to use for the starting point? Enter an old Radio Shack P-Box stereo amplifier kit.

An N-channel JFET has a low bias current when its gate is biased negative to the source. However, this requires either that the gate voltage be biased negative with respect to the source voltage or ...

Despite recent improvements in the performance of RF LDMOS field-effect transistors (FETs), temperature drift and aging continue to affect the efficiency and linearization of power amplifiers using ...

While this op amp may actually have some utility, it is intended mainly as an educational exercise. I guarantee that if you build and experiment with this circuit, you will learn and appreciate what ...
