In RF Energy Harvesting (RFEH), the harvested voltage becomes significantly low when the RF source is far from the receiver or when losses in the rectifier are substantial. Therefore, a charge-pump boost converter is essential to generate a sufficient voltage to operate the subsequent system. Although previous works have proposed individual circuits that apply either gate–source voltage enhancement or threshold voltage reduction, no prior study has combined both techniques in a single design. When combining these techniques, the internal node voltages in the circuit differ significantly from those in conventional designs, requiring careful investigation of optimal connection points. This paper proposes a novel circuit that integrates both techniques to achieve improved performance under ultra-low voltage conditions. Simulation results confirm that the proposed circuit achieves an improvement in start-up response time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e本誌掲載ページ：\u003c\/strong\u003e61-64p\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e原稿種別：\u003c\/strong\u003e英語\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePDFファイルサイズ：\u003c\/strong\u003e915Kバイト\u003c\/p\u003e","brand":"IEEJ-PDF","offers":[{"title":"PDFダウンロード（一般価格440円\/会員価格220円） \/ A4 \/ 4","offer_id":47656272232687,"sku":"IEEJ-AVIC2025C5-PDF","price":440.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-PDF_bumontaikai_63e49e75-d204-4426-9cde-907a8e50fbfa.png?v=1770625056","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-avic2025c5","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
