A CMOS Switched Capacitor Filter Based Potentiometric Readout Circuit for pH Sensing System

A CMOS Switched Capacitor Filter Based Potentiometric Readout Circuit for pH Sensing System

This work presents a potentiometric readout circuit for a pH-sensing system in an oral healthcare device. For in vivo applications, noise, area, and power consumption of the readout electronics play critical roles. While CMOS amplifiers are commonly used in readout circuits for these applications, t...
