Abstract

A clock circuit includes a set of level shifters, a duty cycle adjustment circuit and a calibration circuit. The set of level shifters is configured to output a first set of phase clock signals having a first duty cycle. The duty cycle adjustment circuit is configured to generate a first clock output signal responsive to a first phase clock signal, a second phase clock signal and a set of control signals, and adjust the second duty cycle responsive to the set of control signals or a phase difference between the first phase clock signal and the second phase clock signal. The calibration circuit is configured to perform a duty cycle calibration of a second duty cycle of the first clock output signal based on an input duty cycle, and to generate the set of control signals responsive to the duty cycle calibration.
