Abstract
A Miller-compensated amplifier, having an amplifier input and an amplifier output, comprises a first gain stage, a second gain stage, a third gain stage, and a capacitor. The first gain stage has the amplifier input as a first gain stage input thereto and a first gain stage output. The second gain stage has a second gain stage input, coupled to the first gain stage output, and a second gain stage output. The third gain stage has a third gain stage input, coupled to the second gain stage output, and provides an output voltage at the amplifier output. The capacitor is coupled between the amplifier output and the second gain stage input. The second gain stage amplifies a small signal part of a current received thereby and leaves a DC component thereof substantially the same.
