This work presents a highly linear temperature sensors implemented with SOI Lateral PIN Diodes, for low-power applications, biased on the exponential region of the I-V characteristics. Experimental results are shown for temperatures ranging between 150 K and 400 K, showing that depending on the selected bias currents, the linearity can be improved in comparison to a single SOI PIN diode. Simulations results show that the sensing range can be extended for both lower and higher temperatures maintaining high linearity.
