摘要：A frequency divider is disclosed herein. The frequency divider includes a firstlatch circuit and a second latch circuit coupled to the first latch circuit. Each of the firstlatch circuit and the second latch circuit includes a first level for generating a sourcecurrent, a second level for receiving a pair of input signals and for generating a pair of

output signals, and a third level for receiving the source current and a pair of clocksignals. The second level is coupled between the first level and the third level. The firstlevel includes a first transistor having a source terminal and a substrate both coupled toa source voltage. The third level includes a plurality of transistors controlled by the pairof clock signals. Each transistor in the third level has a source terminal and a substrateboth coupled to ground.
