Abstract
In this paper, a fully integrated, LC-oscillator based buck regulator is presented for low power applications. The proposed design uses a self-resonator as both high-speed clock source and a resonant switch driver for the regulator, which not only achieves significantly improved energy efficiency at 2GHz switching frequency but also delivered a high-quality clock source eliminating requirement of the external high-speed clocks. Measurement on a 65nm testchip shows a wide tuning range from 0.35V to 0.82V with an input voltage 1.1V. The proposed design achieves a peak efficiency of 70.3% and an autonomous clock-less operation. The regulator core area is only 0.079mm 2 .
