Abstract
According to an embodiment, an operational amplifier includes a first amplifier stage coupled between an input node and an intermediate node, a second amplifier stage coupled between the intermediate node and an output node, a compensation capacitor having a first terminal coupled to the intermediate node and a second terminal, and a compensation amplifier coupled between the output node and the second terminal. The compensation amplifier has a positive gain greater than one.
