摘要：
Digital envelope tracking with multilevel supply voltages is performed for wide-bandwidth signals. A digital control component generates a digital control code that facilitates switching of resistor values of one or more resistors coupled between a power amplifier and a supply voltage of plurality of supply voltages. A driver component supplies an envelope voltage of the plurality of supply voltages for the power amplifier as a function of the digital control code.
