Abstract

A circuit having an input amplifier and a second amplifier that provides the circuit with a unity gain crossover frequency that is higher than a unity gain crossover frequency of the input amplifier is provided. The circuit has a control input coupled to a control input of the input amplifier and also has a first current connection and a second current connection. The circuit further includes an additional amplifier that is connected in series with the second amplifier and is controlled by the input amplifier.
