Our goal is to realize artificial intelligence by reproducing brain-cell-like behavior with electronic circuits and hardware, with the aim of supplementing the workforce through autonomous robots. Previously, we proposed a spiking neuron model (P-HCNM) that can be constructed using only standard CMOS processes, but the yield of the separate-excitation model in IC implementation was below 50%. From our analysis, the failure was attributed to the activation of parasitic bipolar transistors caused by voltage increases due to bootstrapping in the circuit. To address this problem, we propose a modified circuit structure that incorporates a discharge path and a bias-current limiting mechanism. The proposed design was fabricated using a 0.18 um CMOS process and verified experimentally. The results demonstrate correct spike operation without latch-up and improved yield in the self-excitation model. Furthermore, simulation results show that the voltage bias error caused by the modification remains within acceptable limits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e本誌掲載ページ：\u003c\/strong\u003e85-88p\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\u003e616K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":47656276295919,"sku":"IEEJ-AVIC2025D5-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_c693ab59-4129-4ad3-b7bf-25b3643d9d64.png?v=1770625090","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-avic2025d5","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
