摘要： Aspects of a method and system for on-demand receiver supply voltage and current are provided. In this regard, strength of a signal received by one or more antennas may be measured and a voltage and/or current supplied to one or more of a LNA, a filter, a mixer and/or a data converter within said receiver may be varied based on the measured signal strength. The voltage and/or current may be varied based on signal strength of in-band and/or out-of-band signals. In this regard, the voltage and/or current may be increased when measured signal strength is above a threshold and decreased when the signal strength is below a threshold. The voltage and/or current may be controlled via a bias voltage determined based on the measurement. Similarly, the voltage and/or current may be controlled via a periodic signal with frequency and/or duty cycle determined based on the measurement.
