Abstract

Example embodiments describe a digital radio-frequency, RF, circuitry comprising a digitally controlled amplifier further configured to receive an RF input signal and a digital control signal, and to output an amplitude controlled output signal; the digitally controlled amplifier comprising one or more common-source amplifying unit cells (300); and wherein a respective common-source amplifying unit cell comprises a sources node (342) connected to a switching circuitry (360) controllable (301) by the digital control signal so as to activate or deactivate the common-source amplifying unit cell; and wherein the switching circuitry comprises a first (370) and second (380) switch configured to connect the source node with a first (390) respective second (391) power supply node when activating respectively deactivating the common-source amplifying unit cell.
