Abstract
An example boosted switch driver circuit includes two branches. The first branch includes a first transistor. The second branch includes a second transistor and a level shifter circuit. One of the transistors is an N-type transistor and the other one is a P-type transistor. The circuit is configured to split an input clock signal between the first branch and the second branch, so that a portion of the input clock signal split to the first branch is provided to the first transistor, and a portion of the input clock signal split to the second branch is level-shifted by the level shifter circuit to generate a level-shifted input clock signal and the level-shifted input clock signal is provided to the second transistor. The circuit is further configured to combine an output of the first transistor and an output of the second transistor to generate an output clock signal.
