提出了一种两级密勒补偿CMOS运算放大器的优化补偿策略。避免右半平面零点的缓冲器的输出电导被有利地用于实现极点-零点补偿。实际上，由于缓冲器的正确选择，可以实现对负载电容引起的极点的补偿，从而提供更好的频率性能。>
An optimized compensation strategy for two-stage Miller-compensated CMOS operational amplifiers is presented. The output conductance of the buffer which avoids the right half-plane zero is profitably used to achieve a pole-zero compensation. Indeed, thanks to a proper choice of the buffer transconductance, the compensation for the pole due to the load capacitor is reached, thus providing better frequency performance. >
