A CMOS differential difference operational mirrored amplifier

Abstract Design of a high-performance differential difference operational mirrored amplifier is presented. The proposed circuit is useful for continuous-time analog signal processing. The circuit is developed using folded cascode amplifier and the floating current source. Several applications including grounded resistor, voltage amplifier, grounded inductor and oscillator circuit are presented. Simulation results for the DDOMA circuit and its applications are given.
