Duty cycle corrector

摘要

The duty cycle corrector for correcting a system clock signal comprises a duty cycle detector and a duty cycle adjuster. The duty cycle detector is configured for detecting a system duty cycle of the system clock signal and generating the first control signal and the second control signal, wherein the first control signal and the second control signal are complementary to each other. The duty cycle adjuster comprises an inverter and the duty cycle adjuster is configured for delaying a change in an input status of the inverter and adjusting of the inverter in accordance with the first control signal and the second control signal.

1. A duty cycle corrector, suitable for correcting a system clock signal, comprising:
a duty cycle detector for detecting a system duty cycle of the system clock signal and accordingly generating a first control signal and a second control signal, the first control signal and the second control signal being complementary to each other; and a duty cycle adjuster, comprising
an inverter configured for generating the system clock signal: and
a partial edge-latching unit configured for delaying a change in an input status of the inverter in accordance with the first control signal by providing a negative feedback between an input terminal and an output terminal of the inverter.
