In Part 1 of this five-part series, we examined FET voltage controlled resistors, basic voltage controlled resistor circuits, and a balanced or push pull voltage controlled resistor (VCR) circuit.

I get somewhat annoyed when I hear engineers who have some real-world experience or exposure casually dismiss a component, especially a passive one, as “simple.” It may be simple in concept or ...

IT is well known that changes in the d.c. characteristics of transistor amplifiers with temperature are particularly severe, and tend to limit the range over which these devices can operate. The d.c.

Many PIC processors require 5-V power while being programmed, yet battery-powered systems may contain low-voltage devices that will be damaged at voltages above their maximum voltage ratings. In ...
