Xie, S. (author), Abarca Prouza, A.N. (author), Theuwissen, A.J.P.A.M. (author)This brief proposes employing each of the classical 4 transistor (4T) pinned photodiode (PPD) CMOS image sensor (CIS) pixels, for both imaging and temperature measurement, intended for compensating the CISs' dark current, and dark signal non-uniformity (DSNU). The proposed temperature sensors rely on the thermal behavior of MOSFETs working in...journal article 2020

Yousefzadeh, B. (author), Makinwa, K.A.A. (author)This article presents a BJT-based temperature-to-digital-converter (TDC) that achieves ±0.25 °C 3 sigma -inaccuracy from -40 °C to +180 °C after a heater-assisted voltage calibration (HA-VCAL). Its switched-capacitor (SC) ADC employs two sampling capacitors and, thus, the minimum number of critical sampling switches, which minimizes the...journal article 2020

Pan, S. (author), Luo, Yanquan (author), Heidary Shalmany, S. (author), Makinwa, K.A.A. (author)This paper describes a high-resolution energy-efficient CMOS temperature sensor, intended for the temperature compensation of MEMS/quartz frequency references. The sensor is based on silicided poly-silicon thermistors, which are embedded in a Wien-bridge RC filter. When driven at a fixed frequency, the filter exhibits a temperature-dependent...journal article 2018
