Patent ID: 10110238

Abstract:
An electronic circuit arranged to receive an oscillating signal and output an output signal at a frequency having a frequency relation with the oscillating signal defined by a divide ratio is provided. The electronic circuit comprises a first frequency divider arranged to receive the oscillating signal and output N frequency divided signals of different phases, a second frequency divider arranged to receive one of the N signals and frequency divide the received signal by a value given by a first control signal provided to the second frequency divider, N latch circuits each being arranged to receive a respective one of the N signals at a clocking input of the respective latch circuit and to receive an output of the second frequency divider at an input of the respective latch circuit, a multiplexer circuit arranged to receive outputs of the N latch circuits and to output a signal, on which the output signal is based, selected from the received signals based on a second control signal provided to the multiplexer circuit, and a control circuit arranged to provide the first control signal and the second control signal based on the divide ratio. A phase-locked loop circuit, a transceiver circuit, a radio station, and a method of frequency dividing an oscillating signal are also provided.
