Abstract
A multistage operational amplifier includes a transconductor input stage, an output stage, and an intermediate stage. A first Miller capacitor is connected between the input and the output of the intermediate stage. A second Miller capacitor is connected between the input of the intermediate stage and an output of the output stage. A current mirror is connected to the output from the intermediate stage to draw a current therefrom.
