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 ...

The LT1819 dual, unity-gain stable voltage feedback op amp has a total harmonic distortion of -85dB at 5 MHz at a voltage output of 2 Vp-p. Current consumption is just 9 mA with a 500_ load. The ...

The voltage-amplifier stage (or VAS) has often been regarded as the most critical part of a power-amplifier, since it not only provides all the voltage gain but also must deliver the full output ...

Download this article in .PDF format This file type includes high resolution graphics and schematics. Feedback systems have a wide range of applications including different types of amplifiers, signal ...

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 ...
