Abstract
A differential two-stage Miller compensated amplifier system with capacitive level shifting includes a first stage differential transconductance amplifier including first and second output nodes and an output common mode voltage, a second stage differential transconductance amplifier including non-inverting and inverting inputs and outputs and an input common mode voltage, and a level shifting capacitor circuit coupled between the first and second output nodes and the non-inverting and inverting inputs for level shifting between the output common mode voltage of the first stage and the input common mode voltage of the second stage.
