The circuit includes a duty control buffer and a duty control voltage generator that receives outputs of the duty control buffer, detects a duty error, and generates control signals. The duty control buffer includes a differential stage including unbalanced first and second differential pairs each differentially receiving input signals, a load element pair connected between output pairs of the first and second differential pairs and a power supply, and a current source stage that supplies respective driving currents to the first and second differential pairs. |
