Abstract
A pulse width compensation circuit may include a voltage control circuit and a pulse width adjustment circuit. The voltage control circuit may sense a voltage level of a first power supply voltage and generate a voltage control signal. The pulse width adjustment circuit may generate an output signal by changing a pulse width of an input signal based on the voltage control signal.
