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.

Combining two TLx431 regulators together to make a programmable gain current mirror that can be also used for a current loop ...

It used to be a rite of passage to be able to do the math necessary to design various bipolar transistor amplifier configurations. This doesn’t come up as often as it used to, but it is still a good ...

Abstract: Despite increasing indium content improves the field-effect mobility of metal–oxide thin-film transistors (TFTs), it is usually accompanied by the deterioration in bias stability. In this ...

Abstract: This work introduces a highly effective and robust design methodology for the concurrent realization of a high-power, integrated reflective transistor-based limiter and a low-noise amplifier ...
