Abstract
The present disclosure provides a method for operating a dynamic pattern generator (DPG) having a mirror array. The method comprises receiving a clock signal, determining a time delay based on the period of the clock signal, determining a first clock signal for toggling a first group of mirror cells in the mirror array, determining a second clock signal, lagging behind the first clock signal by the time delay, for toggling a second group of mirror cells in the mirror array, toggling the first group of mirror cells in the mirror array in response to the first clock signal, and toggling the second group of the mirror cells in the mirror array in response to the second clock signal.
