I have a piezo-resistive pressure sensor which is a current excitation type. I want you to review/redesign my existing circuit. My circuit is working fine and contains current excitation circuit for sensor, Voltage reference circuit for ADC, 24 bit ADc, Microcontroller pic18LF2620, LCD, buttons, voltage regulators, battery. I think my circuit produces error due to Temperature factors.
Need to check/modify,
1. Current excitation must be very steady. So that it should not get affected by input voltage changes, temperature, etc.
2. Reference for ADC must be very steady. Also it should not get affected by input voltage changes, temperatures, etc.
3. Need to take care of EMC, etc
Need to review my existing circuit which I will share it on inbox.
Needed circuit design expert.
