摘要
Low-power, low-voltage, and high-performance requirements are badly needed for operational amplifiers (op-amps) in modern applications. In this brief, a design method for minimizing the settling time in three-stage nested-Miller schemes is presented. As an application example, a CMOS 0.35-mu m voltage follower with 115-dB dc gain and fastest step response to 1% accuracy level, is designed. Circuital simulations demonstrate that the proposed procedure allows the amplifier settling-time/power-consumption ratio to be significantly improved with respect to conventionally designed op-amps.
