Abstract

A monolithic capacitance multiplication circuit serves to reduce the required die area when larger capacitance values are needed such as in filter and loop frequency compensation circuits. A current mirror/cascoding device arrangement reduces the effective series resistance of the multiplier capacitor. As a result, the multiplier topology exhibits improved bandwidth over prior art capacitance multiplier circuits.
