ABSTRACT:
An improved current mirror is described which has utility as either a stand alone current source or as a gain block whenever current gain or transimpedance gain is required. When used as a current source the current mirror exhibits higher output impedance, and when used as a gain block, the current mirror exhibits improved higher frequency performance and high transimpedance gain than prior art current mirrors.
