A BJT-Based CMOS Temperature Sensor with Duty-Cycle-Modulated Output and ±0.5°C (3σ) Inaccuracy from -40 °c to 125 °c

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....

An Accurate BJT-Based CMOS Temperature Sensor With Duty-Cycle-Modulated Output

This paper describes the design of a precision bipolar junction transistor based temperature sensor implemented in standard 0.7-μmCMOS technology. It employs substrate p-n-ps as sensing elements,which makes it insensitive<br/>to the effects of mechanical (packaging) stress and facilitates the use of low-cost packaging technologies. The sensor...
