A Smartphone-based High Sensitivity Impedance Readout Circuit for Milk Adulteration

The proposed work develops a lab-on-chip platform to detect the milk adulteration which exploit the smartphone to overcome the external battery usage and calibration. To have a low cost and convenient platform for sensing, the interface circuit is powered through the smartphone and calibration is done through the customized built Application using Android studio and Arduino IDE.A great accuracy of 0.1Ω change is achieved by this work. The OTA designed has a high GBW of 110 MHz, high gain of 90 dB and very low noise floor .Apart from this, a wide range resistive readout circuit is also implemented which could sense the resistance ranging from 10KΩ-1GΩ.The whole design is analyzed in TSMC 0.18µ technology.
