The proposed architecture consists of the PTAT circuit with the positive slope, the PTAT circuit with the negative slope and a subtractor. The concrete circuit based on the proposed architecture is designed, and evaluated through HSPICE with a set of device parameters of 0.18μm CMOS process. The simulations demonstrate a maximum temperature error of 2.3℃ and the maximum current consumption of 28.7μA under the condition that the temperature range is from -20℃ to 100℃, the sensitivity is 5.2mV/℃ and VDD=1.5V.本誌: 電気学会論文誌C（電子・情報・システム部門誌） Vol.131 No.7 （2011） 特集：平成22年電気学会電子・情報・システム部門大会本誌掲載ページ: 1281-1286 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejeiss/131/7/131_7_1281/_article/-char/ja/ Show more
