Abstract
A pulsed signal generator generates a pulsed signal having a pulse width configured to be equal to a given fraction of a pulse width of a reference clock. A reference current source outputs current having a reference magnitude, and a comparison current source outputs current having a magnitude that is a function of the reference magnitude and the given fraction. A comparison circuit compares a total current output by one of the reference current source and the comparison current source during pulses of the reference clock to a total current output by the other of the reference current source and the comparison current source during pulses of the pulsed signal equal in number to the pulses of the reference clock in order to determine whether the pulse width of the pulse signal is less than or equal to the given fraction of the pulse width of the reference clock.
