摘要：
A rail-to-rad, constant-g, I-volt only, full-CMOS opamp is presented. The opamp has a complementary PMOS/bulk-driven input stage with a feedback circuit to equalize g(m), and a class AB output stage, which provide input and output rail-to-rail operation. HSPICE simulations are performed using BSIM 3.3 models of a 0.8 mu m CMOS process. This opamp has a DC gain of 45.1 dB, unity-gain bandwidth of 1.7 MHz, and phase margin 63.4 degrees.
