Abstract
A duty ratio correction circuit includes: a buffer circuit configured to generate a second signal based on a first signal, the second signal having a DC component corresponding to a first control signal; a waveform shaping section configured to shape a waveform of the second signal to generate a third signal that is a target of duty ratio correction; a first capacitor; and a first charge-discharge control circuit configured to selectively charge or discharge the first capacitor based on the third signal, to generate the first control signal.
