Kertas kerja ini mencadangkan dan menunjukkan penukar rangsangan 65nm proses CMOS cascode single-inductor-dual-output (SIDO) yang outputnya ialah bateri Li-ion dan bekalan voltan rendah 1V untuk penerima pemindahan kuasa wayarles (WPT) RF. Bekalan kuasa 1V digunakan untuk litar kawalan dalaman untuk mengurangkan penggunaan kuasa. Untuk menahan output bateri Li-ion 4.2V, cascode 2.5VI/O PFET digunakan pada peringkat kuasa. Sebaliknya, untuk menjana 1V sambil mengekalkan toleransi 4.2V pada output 1V, cascode 2.5VI/O NFET peringkat output dicadangkan. Keputusan pengukuran menunjukkan kecekapan penukaran sebanyak 87% pada PIN=7mW, ILOAD=1.6mA dan VBAT=4.0V, dan 89% pada PIN=7.9mW, ILOAD=2.1mA dan 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.
