Abstract
A multi-stage amplifier, comprising a first amplifier stage is presented. The output of the first amplifier stage is coupled to a first terminal of a capacitor having a controllable capacitance. The input of a second amplifier stage is coupled to the output of the first amplifier stage and the first terminal of the capacitor. The output of the second amplifier stage is coupled to a second terminal of the capacitor and an output of the multi-stage amplifier. The input of a current sensing circuit is coupled with the output of the multi-stage amplifier. A control signal generator is coupled between the output of the current sensing circuit and a control terminal of the capacitor. The control signal generator provides a control signal to the capacitor in order to control or vary the capacitance of the capacitor.
