According to an embodiment, the system includes a first transistor and a second transistor. The first transistor has a first input node coupled to a first signal input, a first output node coupled to a first common node, and a first reference node coupled to a first reference voltage, A second input node coupled to the input, a second output node coupled to the output of the system, and a second reference node coupled to the first common node. The system further includes a first switch for switchably coupling the first common node to a second reference voltage. |
