The propose circuit consists of a temperature sensing circuit and digital interface circuit. The both circuits are capable of operating at 1.0 V. The propose temperature sensing circuit utilized subthreshold region of MOSFETs. And the propose digital interface circuit converts a current into a time utilizes Current-to-Time Converter (ITC). This digital interface has good characteristics against the temperature dependence, and it does not use approximations. Therefore, these can convert temperatures into digital values accurately. From the evaluation using HSPICE, we could obtain the signals proportional to temperature. Furthermore, I fabricated prototype-chips of temperature sensing circuit on the 0.6 μm CMOS processes, and evaluated it. As the results, I confirmed effectiveness of the proposed circuit. 宮崎大学工学部 Faculty of Engineering, University of Miyazaki 2012-07-30 jpn departmental bulletin paper VoR http://hdl.handle.net/10458/4100 https://miyazaki-u.repo.nii.ac.jp/records/2564 AA00732558 05404924 宮崎大学工学部紀要 Memoirs of Faculty of Engineering, University of Miyazaki 41 85 92 https://miyazaki-u.repo.nii.ac.jp/record/2564/files/engineering41_85-92.pdf application/pdf 1.3 MB 2020-06-21
