a) Using a NTC thermistor with "B=4000K, resistance: 5kN at 25°C" we want to measure the temperature of an environment in the range 50°C - 100°C. Design a suitable circuit for this purpose with "zero" output signal (v) value at 25ºC. Express the output and its temperature-sensitivity in terms of temperature (y=f(T°C) and dy/dT= f(T°C)). Roughly draw y and dy/dT for the given temperature range. (Note: For NTC: RATC=Roexp(B(1/T-1/T)

Question
a) Using a NTC thermistor with "B=4000K, resistance: 5k2 at 25°C" we want to measure the temperature of
an environment in the range 50°C - 100°C. Design a suitable circuit for this purpose with "zero" output signal
|v) value at 25ºC. Express the output and its temperature-sensitivity in terms of temperature (y=f(T°C) and
dy/dT= f(TºC)). Roughly draw y and dy/dT for the given temperature range.
