  • Feedback loop for LC VCO
    Publication number: 20050212611
    Abstract: A voltage-controlled oscillator includes an inductor capacitor (LC) tank; a drive circuit having a current source; and a feedback loop circuit. The feedback loop includes a peak detect circuit to generate a peak detect voltage; a reference voltage generator to generate a single reference voltage; and an operational amplifier, coupled to the peak detect circuit and the reference voltage generator, to generate an analog bias signal to adjust a current of the current source.
