ABSTRACT:
A dividing circuit comprises, connected in a ring, a plurality M of transistor stages, where M is an even integer. Each transistor stage comprises an input node, a clock node and an output node. A tri-state inverter stage has an input node connected to the output node of a preceding transistor stage in the ring, an enable node connected to the clock nodes of the transistor stages, and an output node connected to the input node of a subsequent transistor stage in the ring. Each transistor stage comprises a first pair of transistors of a first conductivity type connected in series between a first voltage level and an output node, and a second pair of transistors of a second conductivity type connected in series between a second voltage level and said output node, wherein control nodes of a first transistor of each said transistor pair are connected together to provide the input node for the stage, and control nodes of a second transistor of each said transistor pair are connected together to provide the clock node for the stage, whereby when an input clock signal is applied to the clock nodes of the transistor stages, an output signal is generated at the output node of the tri-state inverter in which each cycle represents M cycles of the input clock signal.
