The proposed TIA core circuit has wider bandwidth characteristics than the conventional CGFW circuits. The number of post-amplifier stages can be reduced to one by increasing the gain of the TIA core circuit, resulting in low-power operation. Fabricated in a 65 nm bulk-CMOS technology, the proposed TIA circuit achieves a transimpedance gain of 72.2 dBOmega and a bandwidth of 20.9 GHz. Operating at a supply voltage of 1.1 V, the circuit consumes 18.7 mW (=17.0 mA x 1.1 V). The result is a data rate of 25 Gbps with an energy efficiency of 0.75 pJ\/bit. The total layout area, including I\/O pads and DC pads, is 670 um x 580 um (=0.39 mm2), while the TIA core circuit occupies 470 um x 210 um (=0.099 mm2).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e本誌掲載ページ：\u003c\/strong\u003e41-44p\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\u003e2,688K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":47656270201071,"sku":"IEEJ-AVIC2025B5-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_809c907c-6e5b-447e-b7a7-23f97e035652.png?v=1770625028","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-avic2025b5","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
