One of the more common building blocks of a voltage controlled amplifier (VCA) is a differential pair amplifier. For a VCA configuration, the (top) two bases receive a control voltage for gain control ...

A simple linear voltage-controlled amplifier can be constructed with one op amp and two JFETs. The amplifier can achieve an 80-dB dynamic control range with less than ...

Most everyone that has ever purchased an external amplifier is at least familiar with the term voltage gain. Simply, it is the degree to which an amplifier actually ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

You can take an op amp with rare input characteristics and elevate it to achieve higher voltage range, better gain accuracy, higher slew rate, and less distortion than the original op amp. I was ...
