Abstract
A closed loop switch control system and a corresponding method is provided for controlling an impedance of a switch. The switch, which usually comprises a transistor switch, may be part of an external circuit. The system comprises the switch and a control unit coupled to the switch. The control unit is configured to regulate an impedance of the switch to a reference impedance while also enabling a fast switch response time. This is achieved by configuring the control unit to have a frequency response comprising a plurality of dominant poles and at least one zero.
