Abstract

In this paper, we propose mode selector for operating a switching system and regulator of linear system to detect the load current. The proposed mode selector can be a mode switching of linear system and switching system, and it has been proposed to compensate for the disadvantages of regulator of switching system with low efficiency in light load conditions. At light load conditions, the mode selector is possible to provide a high efficiency in light load condition by switching the mode to the regulator of linear system. The mode selector was designed to using a Dongbu Hitek $0.18{\mu}m$ CMOS process.

본 논문에서는 부하전류를 감지하여 스위칭 방식과 선형 방식의 레귤레이터를 동작하기 위한 mode selector를 제안한다. 제안된 mode selector는 선형 방식과 스위칭 방식으로의 모드 전환이 가능하며, 경부하 조건에서 낮은 효율을 갖는 스위칭 방식의 레귤레이터의 단점을 보완하고자 제안되었다. 경부하 조건에서는 선형 방식의 레귤레이터로 mode를 전환함으로써 경부하 상태에서도 높은 효율을 제공할 수 있다. 설계한 mode selector는 동부 하이텍의 $0.18{\mu}m$ CMOS 공정을 이용하였다.
