Abstract
A method and circuit for detecting and clamping current in a ground fault circuit interrupter circuit. In accordance with an embodiment the circuit includes an amplifier connected to a switch, where in the amplifier has an input connected to a first conduction terminal of the switch through a resistor and another input connected to a second conduction terminal of the switch. An output of the amplifier is connected to a control terminal of the switch. The circuit may include a ground fault circuit interrupter engine having an input connected to the first conduction terminal of the switch and another second input connected to the second conduction terminal of the switch.
