our 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 it preferable 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.
