Abstract
An oscillator and method for operation of the oscillator are provided. The oscillator includes a control voltage generator configured to generate a control voltage based on dividing a power voltage that was received, an offset voltage generator configured to generate an offset voltage based on dividing the power voltage that was received, a phase locked loop (PLL) including a varactor circuit configured to modify a capacitance based on the control voltage and the offset voltage, and a calibration logic circuit configured to provide a selection control signal to the control voltage generator based on the oscillation signal, and configured to provide an offset control signal to the offset voltage generator based on the oscillation signal.
