Problem 1: The temperature difference between position 1 and position 2 is to be found. Let x 1 [290K , 310K] denote the temperature at position 1 and x 2 [290K , 310K] denote the temperature at position 2. Temperature at position 1 is to be measured using an integrated temperature sensor with model function H t ITS ( x ) = x A K and temperature at position 2 is to be measured using a thermistor with model function H t thm ( x ) = R e /x , where R = 0 . 075 and = 3000K. ( a ) Show the linear form of the thermistor model function for the given temperature range in which the thermistor is placed in parallel with a linearizing resistor. (14 pts) ( b ) Using the linear thermistor model function obtained above, design a circuit to convert the temperature difference x = x 1 x 2 to voltage...
