ABSTRACT:
Voltage controlled oscillator (VCO) circuits include a VCO and voltage regulator provided on an integrated VCO module, balanced control input for the VCO, buffering of the VCO and frequency multiplication of the VCO output signal. Such improved VCO circuits are especially useful in phase-locked loop (PLL) circuits. Improved PLL circuits are also provided, including a PLL circuit with separate analog and digital grounds.
