摘要：

The power supply rejection ratio (PSRR) of operational amplifiers is analyzed. An analyzing technique based on cuts in subcircuits is presented that allows hand calculation of PSRR of any circuit. In this paper it is shown that the PSRR of the single stage operational amplifier (OTA) has an order of magnitude better PSRR than the commonly used Miller OTA. The analyses are compared with hand calculations and SPICE level-2 simulations on a realized improved Miller OTA structure. © 1990 IEEE
