![]() ![]() My work shows the two stage amplifier with Miller compensation techniques, simulated using LtSpice simulation tool for 180, 130 and 90 nm CMOS technology process. The Miller capacitor creates an undesirable right-half-plane (RHP) zero due a non inverting feedforward signal path is induced in the input of the second stage towards its output, which can be eliminated by using voltage buffer. The LtSpice simulation tool is used to present system result at low capacitive load with different characteristics. The paper represents a design procedure of basic two stage CMOS operational amplifier using Miller compensation technique.
