Abstract
An adjusting circuit of duty cycle includes an edge detecting circuit, a flip-flop connected to the edge detecting circuit, a feedback control circuit connected to the flip-flop and a charge pump circuit connected to the feedback control circuit. The edge detecting circuit detects an edge of an inputted clock signal. The flip-flop sets an outputting terminal thereof at a first level according to a clock signal outputted by the edge detecting circuit. The charge pump circuit controls a duration of the first level outputted the outputting terminal of the flip-flop by charging and discharging a capacitor. The flip-flop sets the outputting terminal thereof at a second level contrary to the first level according to a clock signal outputted by the feedback control circuit. An adjusting method of duty cycle is also disclosed. The adjusting circuit of duty cycle has a simple structure, a stable performance and a fast speed.
