Abstract

An apparatus comprises a radio frequency (RF) transceiver circuit; a phase modulator that comprises digital-to-time converter (DTC) circuitry configured to convert a digital value to a specified signal phase of a signal transmitted by the RF transceiver circuit; low drop out regulator (LDO) circuitry operatively coupled to the DTC circuitry, wherein a bias current of the LDO circuitry is adjustable; and logic circuitry operatively coupled to the LDO circuitry and DTC circuitry, wherein the logic circuitry is configured to set the adjustable bias current of the LDO circuitry according to a digital value input to the DTC circuitry.
