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.

This file type includes high resolution graphics and schematics when applicable. A piezoelectric motor is a linear motor with bidirectional motion. It uses friction to grip the armature while a ...

While choosing an op-amp buffer for a new high-resolution single-supply DAC, a source of negative supply was considered because the buffer op-amp had to provide true zero voltage on its output. Wow ...
