Abstract
A floating gate driver uses a single-end level shifter to translate a set signal and a reset signal induced by a rising edge and a falling edge of a switch signal to a common output terminal to generate an output voltage for a bistable circuit to generate a level shifted switch signal. Under control of a well transient detect signal asserted by detecting noise in the output voltage, a masking circuit between the single-end level shifter and the bistable circuit masks noise in the output voltage. This configuration has lower area penalty and better noise immunity.
