Abstract
A switch provided between a first terminal and a second terminal with a varying cross terminal voltage. The switch contains two transistors, with the source terminal of the first transistor being coupled to the first terminal and a drain terminal of the second transistor being coupled to the second terminal. The gate terminal of the first transistor is coupled to the first terminal, the gate terminal of the second transistor is coupled to the second terminal, and the drain terminal of the first transistor is coupled to the source terminal of the second transistor. Due to such a topology, the cross-terminal voltage across the first and second terminals can be substantially higher than the voltage of the control signal indicating whether the switch is to be in on or off state.
