You are working with a temperature sensor which produces a change in output voltage as temperature is varied. Between O' to 80°C, the output voltage of the sensor changes linearly from 0.2 V to 0.5 V. (a) (10 points) if you are interested only in the temperature range of 20 to 40°C and the ADC has a 0 to 3V input range, design a signal conditioning circuit to maximize the SONR (the temperature sensor's output will be the input of the signal conditioning circuit, and the signal conditioning circuit's output will be applied to the ADC's input). bl 15 points for the circuit designed in part (a), assume the ADC has an 8-bit resolution. If the raw integer output of the ADC is 200, what is the temperature?
