Your boss asks you to contruct a temperature sensorfor measuring the ambient temp outside (-30degreee celcius<= T<= 40 deg. c). You decide to base operation on the change inresistance accociated with a bar shaped piece of SI.
(a) indicate doping and dimensions of your sensor
(b) derive an expression for the sensitivity (dR/dT inΩ/deg celcius) of sensor over operating temp range. Is itpreferable to use low or high dopings? explain.
(c) What are the upper and lower temp limits of op(approx)?explain.
(d) Plot R vs. T of sensor over required temp range ofoperation.
