Abstract
A device for correcting a duty cycle, comprising: a duty adjustor circuit, configured to receive an input clock signal and a tuning signal, to generate an output clock signal; a first charge pump, configured to charge a first capacitor for a predetermined time period to generate a first voltage; a second charge pump, configured to charge a second capacitor for a time period corresponding to the duty cycle of the output clock signal to generate a second voltage; a first sampling and hold circuit, configured to sample the first voltage to generate a first sampled voltage; a second sampling and hold circuit, configured to sample the second voltage to generate a second sampled voltage; and an error amplifier, configured to generate the tuning signal according to a difference value between the first sampled voltage and the second sampled voltage.
