Very low distortion amplifier.

摘要

An operational amplifier and method for making same, with predetermine common mode voltage gain, adapted to form an amplifier and a voltage regulator. The predetermined common mode voltage gain allows for substantially reduced differential mode gain and wider operating bandwidth with little distortion, compared to amplifiers and voltage regulators using operational amplifiers of the prior art. Further, examples of operational amplifiers, having the reduced differential mode gain and predetermined common mode gain, are given for implementation in CMOS and bipolar technologies.
