Abstract:
A level-shifting circuit includes an input device configured to receive an input signal capable of switching between a reference voltage level and a first voltage level, and a set of capacitive devices paired in series with latch circuits. A first capacitive device of the set is coupled with an output of the input device, and each capacitive device and latch circuit pair is configured to upshift a corresponding received signal by an amount equal to a difference between the first voltage level and the reference voltage level.
