ABSTRACT:
A voltage controlled oscillator which, for example, may be utilized in a phase locked loop, includes an odd number (n) of cascaded COS-MOS inverter stages with a feedback path coupling the output of the last stage to the input of the first stage to form a ring configuration. The ring configuration oscillates at a frequency f.sub.1 determined by the transconductances of the inverter stages and the shunt capacitances between the stages. Signals comprising impulses of current having frequency components at f.sub.1 and 2f.sub.1 flow through the power supply inputs of each of the stages as they successively are switched from one state to another. A frequency selective impedance path is coupled between a source of power supply voltage and the power supply inputs of each of the stages to develop a second signal having a frequency f.sub.2 equal to a multiple nf.sub.1 or 2nf.sub.1. The voltage applied to the commonly connected power supply inputs may be controlled to control f.sub.1 and, consequently, f.sub.2.
