1. A wireless device comprising:
a transceiver configured to process radio-frequency signals;
an antenna in communication with the transceiver configured to facilitate transmission of an amplified radio-frequency signal;
a voltage regulator; and
a voltage selection module coupled to the transceiver and the voltage regulator, the voltage selection module including an analog voltage input coupled to an analog voltage source, a digital based voltage input coupled to a digital based voltage source, and a control component coupled to the analog voltage input and the digital based voltage input, the control component configured to select a first voltage received from the analog voltage input or a second voltage received from the digital based voltage input to provide as a reference voltage to the voltage regulator, the control component configured to receive a first signal indicative of whether the first voltage from the analog voltage input exceeds a threshold voltage and to receive a second signal indicative of whether to select the second voltage from the digital based voltage input as the reference voltage, the control component configured to select the first voltage or the second voltage based on one or more of a value of the first signal and a value of the second signal, the control component further configured to provide the reference voltage to the voltage regulator.
