초록
This paper presents a balanced CMOS complementary folded cascode OP-AMP topology that achieves improved DC gain using the gain boosting technique, a high unity-gain frequency and improved slew rate using the CMOS complementary cascode structure and a high PSRR using the balanced output stage. Bode-plot measurements of a balanced CMOS complementary folded cascode OP-AMP show a DC gain of 80dB, a unity-gain frequency of 110MHz and a slew rate of
