Abstract

In this paper, the proposed sensor utilizes the temperature dependency of MOSFET and BJT for designing of this sensor. The voltage or current across MOSFETs and BJT always varies with the temperature, but the challenge in this project is to design these types of sensors to linearize this variation. This task is accomplished by proper selection of circuit architecture by adjusting W/L Ratio of the transistors and choosing the proper resistor value so that the non-linearity can be reduced. After achieving the linearity, readout circuit is designed for to digitize the obtained temperature information. The proposed temperature sensor is simulated in Cadence Analog Design Environment with GPDK180nm library.
