Abstract

A fully integrated buck regulator for ultra-low voltage application is presented featuring (1) an ultra-high switching frequency at 2GHz with small inductor size at low load current and (2) a resonant switching technique rendering significant efficiency improvement. With small on-chip inductors, the test chip shows a wide voltage tuning range of 0.3-0.86V, at 10-40mA low current, up to 73% efficiency and only occupies 0.073mm2 in a 65nm CMOS process.
