Classification: CPC G  H | IPC G  H

Claim 8:
9. A method of voltage regulation in a front end system, the method comprising:
generating a reference voltage using a reference voltage circuit that is powered by a power supply voltage;
selectively enabling a plurality of circuit blocks using a plurality of enable signals each corresponding to one of the plurality of circuit blocks, the plurality of circuit blocks including a fuse circuit, a radio frequency circuit, and a digital circuit;
generating a programmable regulated voltage based on the reference voltage using a programmable voltage regulator; and
providing the programmable regulated voltage to the plurality of circuit blocks, and setting a voltage level of the programmable regulated voltage based on a selection of the circuit blocks that are enabled, including setting the programmable voltage level to a high voltage level when the fuse circuit is enabled and to a low voltage level when the digital circuit is enabled and the fuse circuit and the radio frequency circuit are disabled.
