Analysis And Design Of Ptat Temperature Sensor In Digital CMOS VLSI Circuits
Adam Gołda, Andrzej Kos · 2006
The paper presents theoretical analyses, simulations and design of a PTAT (proportional to absolute temperature) temperature sensor that is based on the vertical PNP structure and dedicated to CMOS VLSI circuits. Performed considerations take into account specific properties of materials that forms electronic elements. The electrothermal simulations are performed in order to verify the unwanted self-heating effect of the sensor
