Abstract:
A voltage control circuit comprising:at least one voltage controlled oscillator; andat least one voltage controller connected to said voltage controlled oscillator, said voltage controller comprising:a) at least one PMOS T-gate circuit having a fixed positive voltage input, a positive adjustable control voltage input, and a control signal input for supplying a control signal to the PMOS T-gate circuit,b) at least one NMOS T-gate circuit having a fixed negative voltage input, a negative adjustable control voltage input, and a control signal input for supplying the control signal to the NMOS T-gate circuit,c) a positive voltage output connected to said voltage controlled oscillator and said PMOS T-gate circuit for supplying an output voltage to said voltage controlled oscillator, andd) a negative voltage output connected to said voltage controlled oscillator and said NMOS T-gate circuit for supplying an output voltage to said voltage controlled oscillator;wherein a delay of said voltage controller oscillator is controlled by said positive voltage output and said negative voltage output by supplying said control signal to said voltage controller.
