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

Yousefzadeh, B. (author), Heidary Shalmany, S. (author), Makinwa, K.A.A. (author)This paper presents a precision CMOS temperature-to-digital converter (TDC), which senses the temperature-dependent base-emitter voltage of substrate PNPs. Measurements on 20 samples from one batch show that it achieves an inaccuracy of ±60 mK (3σ) from-55 °C to +125 °C, after a single room-temperature trim. This state-of-the-art result is...journal article 2017
