Low-cost temperature sensors in CMOS technology

Temperature greatly affects the performance of integrated circuits, and so temperature sensors are often necessary to ensure reliable operation and stable performance. The goal of the work described in this thesis is to realize a temperature sensor in CMOS technology that can be produced at low cost. In the first step, a temperature sensor is...

A BJT-Based Temperature-to-Digital Converter with ±60 mK (3 σ) Inaccuracy From-55 °c to +125 °c in 0.16-μm CMOS

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...
