ABSTRACT:
A frequency divider circuit is provided having an even number of amplifier stages connected in series with the output of the last amplifier stage connected to the input of the first amplifier stage; and modulating means responsive to an input signal to be frequency divided, for modulating the propagation delay through each of the amplifier stages about the period of the input signal to be divided, such that when propagation through the odd amplifier stages increases, the propagation through the even amplifier stages decreases. The frequency divider circuit can be used as a pre-scaler of a radio receiver circuit.
