본 논문에서는 RF 무선 전력 전송(WPT) 수신기를 위한 리튬 이온 배터리와 65V 저전압 공급 장치를 출력하는 1nm CMOS 공정 캐스코드 SIDO(단일 인덕터 이중 출력) 부스트 컨버터를 제안하고 시연합니다. 1V 전원은 내부 제어 회로에 사용되어 전력 소모를 줄입니다. 4.2V 리튬 이온 배터리 출력을 견디기 위해 전원단에는 캐스코드 2.5VI/O PFET가 사용됩니다. 반면, 1V 출력에서 4.2V 허용오차를 유지하면서 1V를 생성하기 위해 캐스코드 2.5VI/O NFET 출력단이 제안되었습니다. 측정 결과 87%의 변환 효율을 보여줍니다. PIN=7mW, IILOAD=1.6mA 및 VBAT=4.0V, 89% PIN=7.9mW, IILOAD=2.1mA 및 VBAT= 3.4V.

Abstract: This paper proposes and demonstrates a 65nm CMOS process cascode single-inductor-dual-output (SIDO) boost converter whose outputs are Li-ion battery and 1V low voltage supply for RF wireless power transfer (WPT) receiver. The 1V power supply is used for internal control circuits to reduce power consumption. In order to withstand 4.2V Li-ion battery output, cascode 2.5V I/O PFETs are used at the power stage. On the other hand, to generate 1V while maintaining 4.2V tolerance at 1V output, cascode 2.5V I/O NFETs output stage is proposed. Measurement results show conversion efficiency of 87% at PIN=7mW, ILOAD=1.6mA and VBAT=4.0V, and 89% at PIN=7.9mW, ILOAD=2.1mA and VBAT=3.4V.
