  • Abstract
    In this paper, an advancement to compensate multistage operational amplifiers is presented. High-gain and highspeed operational amplifiers can be realized with this approach. One example of such a high-gain amplifier with a unity-gain frequency of 693 MHz and DC gain of 128.8dB is presented. The high-speed settling is mainly reached by dominant Miller compensation via 4 stages.
