The DC-DC converter was fabricated using a standard 65 nm CMOS process and has a 1.1 mm2area. Its output voltage drops to 1.2 V from 2.5 V-3.6 V input, with an output ripple voltage of about 10 mV. To decrease the size of the external device while retaining high efficiency, a 2 MHz switching frequency and 2.2 μH inductance were chosen. Power efficiency exceeds 80% for output current ranging from 50 to 850 mA.","PeriodicalId":198168,"journal":{"name":"2022 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115264873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finally, the pulse driven method is determined as the reliable light-feeding design method. The system made of pulse driven fiber-coupled laser diode has better stability and reliability.
