Classification: CPC G  H | IPC G  H

Claim 10:
11. A mobile device comprising:
a transceiver configured to generate a radio frequency signal;
a power management system configured to generate a power supply voltage; and
a front end system including a reference voltage circuit configured to receive power from the power supply voltage and to generate a reference voltage, a plurality of circuit blocks each selectively enabled by a corresponding one of a plurality of enable signals, and a programmable voltage regulator configured to generate a programmable regulated voltage based on the reference voltage and to provide the programmable regulated voltage to the plurality of circuit blocks, the plurality of circuit blocks including a radio frequency circuit configured to process the radio frequency signal and a fuse circuit, the programmable regulated voltage having a voltage level that changes based on a selection of the circuit blocks that are enabled by the plurality of enable signals, the programmable voltage level operating at a first voltage level when the fuse circuit is enabled and operating at a second voltage level less than that first voltage level when the radio frequency circuit is enabled and the fuse circuit is disabled.
