Abstract: A phase interpolator includes a control circuit configured to generate a selection control signal that corresponds to a selected coarse phase interval, and generate a weight setting signal for generating a phase interpolation clock signal with an interpolated phase within the coarse phase interval; a phase selector configured to receive a plurality of inversion delay clock signal pairs, select at least two inversion delay clock signal pairs from the plurality of inversion delay clock signal pairs based on the selection control signal, select and output a selection delay clock signal pair corresponding to the coarse phase interval from the selected at least two inversion delay clock signal pairs; and a phase mixer configured to receive the selection delay clock signal pair from the phase selector and generate the phase interpolation clock signal based on the weight setting signal.

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.
