Huang, Zhenyan (author), Tang, Z. (author), Yu, Xiao Peng (author), Shi, Zheng (author), Lin, Ling (author), Tan, Nick Nianxiong (author)This brief presents a 0.65% relative inaccuracy CMOS temperature sensor with a duty-cycle-modulated (DCM) output. It uses a BJT-based front-end to generate a proportional to absolute temperature voltage (V_{PTAT}) and a complementary to absolute temperature voltage (V_{CTAT}), which are then modulated to a digital-friendly duty-cycle output....journal article 2021

Tang, Z. (author), Fang, Yun (author), Yu, Xiao Peng (author), Tan, Nick Nianxiong (author), Shi, Zheng (author), Harpe, Pieter (author)This work presents an energy-efficient diode-based CMOS temperature sensor. It is based on the capacitively biased diode (CBD) working principle and can operate with a 1-V supply voltage. Instead of using a separate CBD front-end and ADC, a new architecture is proposed in which the CBD front-end is directly embedded into the 1st stage of a 1...journal article 2021

(author), He, Yan Bing (author), Liu, Dongqing (author), Li, Hai (author), Shi, Ruiying (author), Li, Baohua (author), Kang, Feiyu (author)Through a facile sodium sulfide (Na<sub>2</sub>S)-assisted hydrothermal treatment, clean and nondefective surfaces are constructed on micrometer-sized Li<sub>4</sub>Ti<sub>5</sub>O<sub>12</sub> particles. The remarkable improvement of surface quality shows a higher first cycle Coulombic efficiency (≈95%), a significantly enhanced cycling...journal article 2017
