Abstract
A level-shifter circuit operates to shift an input signal referenced to a first set supply voltages to generate an output signal referenced to a second set of supply voltages. The output signal from the level-shifter circuit is latched by a latching circuit. A logic gate has a first input configured to receive the input signal, a second input configured to receive a feedback signal and an output coupled to a input of the level shifting circuit. A feedback circuit has a first input configured to receive the output signal, a second input configured to receive the input signal and an output configured to generate the feedback signal. The feedback circuit operates to sense an uncontrolled switching event of the output signal occurring in the absence of a switching of the input signal and apply, in response thereto, the feedback signal to cancel the uncontrolled switching event.
