Q4) Design a complete amplifier circuit to connect a pH sensor to a microcontroller that accepts values between 0.5 and 3V. For each component, explain its function, the required parameters of the component, and the reason behind that. The electric potential equation for the pH electrode can be expressed as: E=0.057+[nF2.303(RT)][7pH] F=96500C/mol;R=8.31J/(molK);n=1. Calculate the sensor sensitivity and its full range potential.
