ABSTRACT:
The voltage-controlled oscillator (VCO) of the present invention is designed with reduced sensitivity to power supply voltage variations. The VCO includes multiple inverter stages with dc supply inputs tied to a filtered control dc signal, and a disabling circuit for disabling oscillation. The disabling circuit includes a disabling gate connected to the input to said inverter stages and an enabling gate connecting to the output of the inverter stages for enabling transmission of output from the VCO.
