Abstract

A prescaler system (100) has a prescaler circuit (102) coupled to a divider (104), wherein the divider includes an improved dynamic flip flop divider (118). The divider (118) includes a TSPC nine-transistor D-flip-flop (10). The divider further includes a tenth transistor such as N channel device (41) having a source coupled to ground (43), a drain coupled to a junction between a drain of a P channel device (34) and a drain of another N channel device (37). The divider also includes an eleventh transistor such as N channel device (42) having a source coupled to ground and a drain coupled to a junction between the drain of a P channel device (35) and the drain of a N channel device (39), the junction providing a feedback signal to a N channel device (36), wherein the eleventh transistor further has a gate coupled to the output signal (/Q.sub.A).
