Integrating power management on RF chips

摘要

Power supplies are part and parcel of elec-tronic circuits and are needed in a variety of forms to drive these circuits. Some familiar terms include dc-dc converters, battery chargers, voltage regulators, and voltage references. Normally, these supplies are external to the semiconductor chips, modules or circuit boards they are driving. In fact, with growing complexities of circuits, each chip, module or board requires several different voltages to operate. Thus, seeing multiple dc-dc converters and voltage regulators on a single circuit board is not uncommon.
