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

Xu, L. (author), Huijsing, J.H. (author), Makinwa, K.A.A. (author)This paper presents a fully integrated ±4A current sensor that supports a 25V input common-mode voltage range (CMVR) while operating from a single 1.5V supply. It consists of an on-chip metal shunt, a beyond-the-rails ADC [1] and a temperature-dependent voltage reference. The beyond-the-rails ADC facilitates high-side current sensing without...conference paper 2018
