Abstract
A duty cycle detection circuit, comprises a charge storage component and compare logic. The charge storage component has at least one capacitor, at least one switch, and, at least one current source. A clock signal is used to operate the at least one switch for charging the at least one capacitor using the at least one current source. The charge storage component outputs a first signal indicative of an amount of charge stored when the clock signal is logic high and a second signal indicative of an amount of charge stored when the clock signal is logic low. The compare logic compares the first signal and the second signal to determine a duty cycle for the clock signal.
