Abstract
A digitally-controlled power amplifier (DPA) includes a radio-frequency (RF) clock input, an amplitude control word (ACW) input, and a plurality of DPA cells. The RF clock input is arranged for receiving an RF clock. The ACW input is arranged for receiving a digital ACW signal. The DPA cells are coupled to the RF clock and the digital ACW signal, wherein at least one of the DPA cells is gradually turned on and off in response to at least one bit of the digital ACW signal.
