ABSTRACT:
An odd number of cascaded inverter stages are connected in a ring configuration. Each stage has a control terminal associated therewith. The signal propagation delay time through a particular stage is controlled by the application of control signals to the control terminal. The frequency of the output signal is determined by the delay per stage and the number of stages in the ring configuration. The output signal can be taken from a point between any two cascaded stages in the ring.
