Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

Question: How do I design a circuit with an accurate current output into a nonlinear load resistance? Answer: It’s easy to make current output devices. A number of simple circuits can deliver unipolar ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

A high-performance, microstepping driver for controlling two and four-phase stepper motors has been introduced by Astrosyn International Technology. The low cost P402 features an advanced bipolar ...
