A Fully Integrated Buck Regulator With 2-GHz Resonant Switching for Low-Power Applications.

This paper presents a fully integrated buck regulator design for low-power applications. In order to enable the usage of on-chip inductor for low load current 10-40 mA, the proposed buck regulator is designed with an ultra-high switching frequency at 2 GHz, which is the highest switching frequency reported so far. To reduce the power switch losses, resonant switching scheme is utilized to save the...
