中文摘要	A low-voltage, low-power, and high-gain rail-to-rail operational amplifier (OpAmp) is presented. The replica-amplifier gain enhancement technique is applied to improve the DC gain of the amplifier, which does not degrade the output swing and is very suitable for low-voltage applications. In a 0.18 mu m standard CMOS process, a 1 V OpAmp with rail-to-rail output is designed. For a load capacitance of 5 pF, simulation by HSPICE shows that this OpAmp achieves an effective open-loop DC gain of 65.9 dB, gain bandwidth of 70.28 MHz, and phase margin of 50 degrees with a quiescent power dissipation of 156.7 mu W.
