Abstract
Embodiments of an RFIC and methods for same and mobile terminals can internally reduce an input voltage to provide a prescribed voltage to a radio frequency transceiver. Embodiments of an RFIC can have a high efficiency and/or a low noise. In one embodiment, a device can include a PMIC and an RFIC. The RFIC can include an RF transceiver to carry out an RF transmission and an RF reception, a DC-DC converter to lower a voltage provided by the PMIC, and an LDO regulator to regulate the lowered voltage to a fixed voltage used by the RF transceiver.
