  • Duty cycle control circuit and associated method
    Patent number: 5455530
    Abstract: A duty cycle control circuit, and an associated method, generates an output clock signal having a duty cycle which differs by a desired amount with the duty cycle of an input clock signal. Offset bias signal circuitry generates an offset bias signal which offsets a copy clock signal and an inverted copy clock signal relative to one another by a selected offset bias. The duty cycle of the output clock signal differs with the duty cycle of the input clock signal by an amount which is related to the amplitude of the offset bias signal.
