Abstract
A transmitter and a method for dynamically setting a current mode of the transmitter are provided. The transmitter includes a digital signal processing (DSP) circuit and a radio frequency (RF) circuit. The DSP circuit is configured to determine a target current mode by selecting one of multiple candidate current modes of the transmitter according to instantaneous transmitting (TX) information, wherein the instantaneous TX information includes at least one of a resource block (RB) information, a modulation and coding scheme (MCS), and an orthogonal frequency-division multiplexing (OFDM) type of an instantaneous TX signal. The RF circuit is configured to output the instantaneous TX signal, wherein at least one supply voltage and at least one bias voltage of a power amplifier (PA) of the RF circuit is controlled according to the target current mode. More particularly, the multiple candidate current modes correspond to different target power consumptions of the transmitter, respectively.
