Design of High Gain CMOS Folded Cascode Operational Amplifier

Abstract:

A high-gain folded cascode operational amplifier is presented. Structure of folded cascode operational amplifier and manual calculations are discussed in detail. Folded cascode structure for the input stage is adopted. Folded cascode structure can increase the gain and the value of PSRR. Folded cascode structure can also allow self-compensation at the output. The operational amplifier is designed in 0.35μm CMOS process with 5V power supply. The operational amplifier has high-gain and work steadily. The results of SPICE simulations are shown that the operational amplifier achieved dc gain of 110dB with unity-gain bandwidth of 74.3MHz and phase margin of 54.4 degree.
