摘要：

Two simple schemes for boosting significantly the open loop gain of one stage op-amps without essential degradation of the phase margin are discussed. These are based on low voltage active current mirrors using multiple cascoded auxiliary amplifiers to achieve extremely high output resistance. Post-layout simulations show that open loop gain greater than 300dB with phase mar-gin greater 60 degrees can be achieved in 0.5 mu m CMOS technology.
