Abstract
In some embodiments, a method may include receiving an input signal at an input stage of a circuit and amplifying the input signal using an amplifier of the circuit to produce a level-shifted output signal. The method may further include selectively controlling switches of an active load coupled to the input stage based on the level-shifted output signal to turn off current flow between transitions in the input signal.
