ABSTRACT:
An array oscillator circuit is disclosed herein. The array oscillator circuit includes a plurality of ring oscillators, each ring oscillator having a plurality of buffer stages for generating output signals on a like plurality of oscillator output ports. Interconnections are provided between each of the plurality of ring oscillators and at least one other of the plurality of ring oscillators such that the plurality of ring oscillators oscillate at identical frequencies and such that the output signals on the each ring oscillator's plurality of oscillator output ports have a phase offset from the signals generated on corresponding ones of the other ring oscillator's oscillator output ports. A multiplexer provides an electrical connection to a selected one of the plurality of oscillator output ports of the plurality of ring oscillators.
