SoC 전원 관리를 위한 인덕터와 커패시터 내장형 100㎒ DC-DC 부스트 변환기

초록

his paper presents a design of a high performance DC-DC boost converter as a power module for SoC designs. It applied to this chip that reduced inductor and capacitor for integrating on a chip, and it operates with a switching frequency of 100㎒. It has reliability and stability in high switching frequency. The controller of DC-DC boost converter is designed by voltage-mode control method and compensated properly. The designed DC-DC converter is fabricated with the 0.18㎛ standard CMOS technology with a thick-gate oxide option. The overall die size is 8.14㎟, and controller size is 1.15㎟. The converter has the maximum efficiency over 76% for the output voltage of 4V and load current larger 300㎃. The load regulation is 0.012% (0.5㎷) for the load current change of 100㎃.
