摘要
An integer frequency divider capable of achieving a 50% duty cycle includes a source clock input end that provides a source clock, and two or more latches connected in series according to a connection order. Each of the latches includes: a signal input stage, configured to receive an input signal; a clock receiving stage, configured to treat the source clock as an input clock and an inverted clock of the source clock as an inverted signal of the input clock when the latch corresponds to an odd number in the connection order, and to treat the inverted clock as the input clock and the source clock as the inverted signal of the input clock when the latch corresponds to an even number in the connection order; and a signal output stage, configured to output an output signal according to the input signal and the source clock.
