A guide to using FETs for voltage controlled circuits, Part 2

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.

Current Limiter Offers Circuit Protection with Low Voltage Drop

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

High-Voltage Integrated Circuits

What are HVICs? High-voltage integrated circuits (HVICs) translate low-voltage control signals to levels that are suitable for driving power switches in high-voltage applications. HVICs also can ...

A guide to using FETs for voltage controlled circuits, Part 1

Editor’s note: I am so happy that there are still companies around that create precision, discrete transistors in our industry; Linear Integrated Systems is one of the best I have encountered. There ...
