Indirect Miller effect based compensation in Low power two-stage operational Amplifiers

In this paper a novel compensation method for low power two-stage operational Amplifiers is proposed. The proposed model is used 50 nm CMOS technology and employs a 50 femto Farad capacitor as the compensation capacitor. Although the method uses Miller effect compensation as the compensation method, the compensation capacitor plays its rule in an indirect way. The proposed method has simulated and the results has compared to the conventional cascode and an improved miller compensation miller compensationmodel. Simulation results show that the proposed method is made a proper stability, bandwidth and settling time, where the other methods are unstable in the same technology.
