Abstract
A multi-stage amplifier utilizes capacitive nesting of three or more amplifier stages in combination with multiple feed-forward paths to achieve frequency compensation. Two stages (A.sub.M and A.sub.O) in cascade are first nested with a pole-splitting capacitor (C1) to form a stable device. A stable three-stage amplifier is then created by nesting the two-stage device and a further stage (A.sub.I) with another pole-splitting capacitor (C2) where feed-forward paths are provided from the further stage to both of the other stages.
