Abstract

Exemplary embodiments include an electronic frequency-divider circuit comprising a multi-phase generator circuit configured to: receive an oscillating input signal having a frequency f; determine an integer divide ratio Q based on a first control signal input; and based on the oscillating input signal, generate an N-phase output signal having a frequency f-divided-by-M, wherein M is an integer and adjacent phases of the N-phase output signal are separated by 360-divided-by-(M-times-Q) degrees. The divider circuit can also include a control circuit configured to receive a control input and, based on the control input: provide the first control signal to the multi-phase generator circuit; and select a particular phase of the N-phase output signal. Exemplary embodiments also include a phase-locked loop circuits, transceiver circuits, radio stations, and methods of frequency-dividing an oscillating signal.
