ABSTRACT:
A high frequency divider circuit for producing output signals of half the frequency of an input clock signal includes two identical circuit sections, each producing an output signal and its complement. The circuit sections are connected to each other so that the output signals of one circuit section serve as input signals to the other circuit section. Each circuit section contains a load transistor which is controlled by one of the clock signal and the clock signal complement, and a switch transistor which is controlled by the other of the clock signal and the clock signal complement. The inventive circuit exhibits a reduced RC time constant for each circuit section and an increased output signal swing between the output signals and their respective complements, as contrasted with prior art frequency dividers, thereby increasing the overall circuit response time and its ability to operate at high frequencies.
