Abstract:
1. A method comprising: in response to determining that a radio-frequency receiver is connected to an external power source, setting a circuit configuration of an analog circuit component of an analog signal-processing circuit of the radio-frequency receiver to a full-power configuration to generate a full-power-consumption radio-frequency receiver output signal; and in response to determining that the radio-frequency receiver is not connected to an external power source, setting the circuit configuration of the analog circuit component to a power-saving, scaled-down power configuration to generate a reduced-power-consumption radio-frequency receiver output signal encoding content to be played back to a radio-frequency receiver end user; wherein switching the configuration of the analog circuit component between the full-power configuration and the power-saving, scaled-down power configuration comprises activating or de-activating a first part of the analog circuit component, wherein a second part of the analog circuit component is active in both the full-power configuration and the power-saving, scaled-down power configuration, and wherein switching between the full-power and the power-saving, scaled-down power configuration comprises activating the gate of a power control transistor to interconnect two internal nodes of the signal processing circuit.
