Abstract

A three stage amplifier is provided and the three stage amplifier comprises a first gain stage, a second gain stage and a third gain stage wherein said first stage receives an amplifier input signal and said third gain stage outputs an amplifier output signal. The amplifier includes a feedback loop having a current buffer and a compensation capacitance provided from the output of said third gain stage to the output of the first gain stage. In addition, an active left half plane zero stage is embedded in said feedback loop for cancelling a parasitic pole of said feedback loop.
