Abstract: A circuit includes a second voltage converter electrically coupled to a comparator and first voltage converter. The first voltage converter receives first and second clocks and an input signal at a first voltage and generates an intermediate signal at a second voltage based on the input signal and the first and second clocks. The second voltage converter receives the intermediate signal, the second clock, and a comparison signal and generates an output signal at a third voltage based on the intermediate and comparison signals and the second clock. The comparator receives a reference voltage, the output signal, and the first clock, compares the reference voltage and output signal, and generates the comparison signal based on the first clock and the comparison of the reference voltage and output signal. The second voltage converter adjusts the third voltage of the output signal to approach the reference voltage based on the comparison signal.
