See Part 1, Part 2, and Part 3 of this series. The previous FET circuits pertained to voltage-controlled signal amplitude circuits. That is, the input signal’s amplitude can be changed at the output ...

Low-voltage CMOS analog circuit design has emerged as a critical area of research, driven by the dual imperatives of energy efficiency and high-performance signal processing. This discipline focuses ...

This video explains how transistors work as switches and amplifiers in electronic circuits. Transistors control the flow of ...

Supertex introduces the MD7120, a high voltage, high speed, N-channel, full-bridge power MOSFET driver for use in Class-D audio amplifiers. Supertex, a specialist in high voltage analogue and mixed ...

This article is part of the Ideas for Design Series: Vol. 3, No. 7. This simple, robust, and low-cost signal generator, based on the LM386 power amplifier IC, provides a trio of audio-band signals ...

Mark Levinson has announced it is now shipping the No320S Preamplifier. A direct descendant of the critically acclaimed No32 Reference Preamplifier, the No320S features audio circuits, controls, ...

For a long time, I have thought that pulse generator outputs should not have adjustable amplitude and offset. Instead, they should have an adjustable top value and a separately adjustable bottom value ...

If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.
