Systems and methods for switching between voltages are provided. One system includes an output, first and second switches coupled to the output. The system also includes a first transmission gate coupled to the first switch and a second transmission gate coupled to the second switch. One method includes receiving, at the first transmission gate, a first pair of complementary voltages and receiving, at the second transmission gate, a second pair of complementary voltages. The method further includes selecting the smallest voltage amongst both pairs of complementary voltages and outputting a third pair of complementary voltages. In one method, the first pair of complementary voltages includes a first negative voltage and a positive voltage, the second pair of complementary voltages includes a second negative voltage and the positive voltage, and the third pair of complementary voltages includes the smaller of the first and second negative voltages and the positive voltage.
