Abstract
Embodiments herein disclose an inductor-capacitor voltage-controlled oscillator VCO circuit. The LC-VCO circuit includes a center tapped inductor connected in parallel with a varactorless capacitor bank, where the LC tank circuit resonates to produce an oscillating voltage; and a control circuit connected to a varistor capacitance circuit that comprises a voltage-controlled transistor based variable resistor in series with at least one capacitor, the varistor capacitance circuit being connected in parallel with the LC tank circuit and to a negative trans-conductance circuit. The control circuit includes an error amplifier and a conversion circuit configured to generate an output control voltage based on an input phase locked loop (PLL) control voltage, the output control voltage controlling a value of a capacitance for the varistor capacitance circuit through the variable resistor.
