Abstract
Systems and methods for reducing parasitic current leakage. A switch includes a source resistor, a first transistor, a second transistor, and a midpoint transistor. The midpoint transistor is located in between the first transistor and the second transistor. The midpoint transistor is maintained at a low voltage in response to the switch being in a non-conductive state, and the low voltage is less than or equal to an output voltage of the switch.
