摘要： A method and a supply modulator (SM) are provided for supplying power from a wireless transmitter to a radio frequency (RF) power amplifier. A power control signal input from a modem is received. A reference voltage is determined. An operating mode of the SM is changed by controlling a level of the reference voltage. A voltage is determined based on the level of a reference voltage. When the operating mode of the SM is an ET mode, a first output signal from a linear regulator and a second output signal from a switching regulator are combined to obtain a combined result, and the combined result is output. The first output signal is based on the voltage. When the operating mode of the SM is an APT mode, the voltage based on the reference voltage is output.

摘要： A voltage controlled oscillator (VCO) in a frequency synthesizer generates an output signal having a target frequency by being coarse tuned in accordance with a channel code derived through a binary tree search. Thereafter, the output signal of the VCO may be further tuned using a phase lock loop (PLL) circuit. Each stage of the binary tree search includes a comparison step that determines a channel code bit, and another step that confirms that the channel code converges to a final channel code within an established stage range value.
