In accordance with embodiments of the present disclosure, a circuit may include a transmission switch and a dummy switch coupled at its output to the output of the transmission switch. The transmission switch may be configured to be selectively enabled and disabled based on a control signal received at a gate of the transmission switch. The transmission switch may be further configured to receive a first polarity of a differential signal at its input and pass the first polarity of the differential signal to its output when enabled. The dummy switch may be configured to be disabled and to receive a second polarity of the differential signal at its input, the second polarity of opposite polarity of the first polarity.
