I continue to design analog circuits just in case it turns out that computers are a passing fad. A recent design project called for a πΩ resistor, and I was surprised that I could not find one in ...

Designed for use in automated power supply calibration circuits, the DS3904 nonvolatile, digital resistor contains three low-temperature-coefficient digital resistors with 128 user-selectable ...

Measuring extremely high dc voltages of 10 kV or more usually requires a suitably equipped high-voltage ohmmeter or a digital multimeter and high-voltage divider, along with the proper safety ...

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.
