Abstract
A dividing circuit comprises a plurality (N) of transistor stages connected in a ring. Each stage comprises a first pair of transistors of a first conductivity type connected in series between a first voltage level and an output node, 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 an input node for the stage, and control nodes of a second transistor of each said transistor pair are connected together to provide a clock node for the stage, wherein the input node of each stage is connected to the output node of a preceding stage whereby an output signal is generated at each of said output nodes, each cycle of the output signal representing N cycles of a clock signal applied to said clock nodes of the stages, the output signal having a duty cycle that is closer to 50% than a duty cycle of said clock signal.
