Design of Portable pH Detection System Based on ISFET

GU Peng;DING Qi-sheng;College of Electrical Engineering and Automation/Jiangsu Normal University;  
In this paper, a p H detection system based on ion sensitive field transistor(ISFET) is proposed. REFET and ISFET are introduced to form differential pairs to realize temperature compensation for ISFET and reduce non-linear distortion. The readout circuit with current readout mode is used to effectively reduce the system power consumption. Firstly, the overall structure of the system is introduced, and the working principle of ISFET/REFET and current mode readout circuit is emphatically expounded. Then it introduces the main control chip of the system and the realization methods of data reading,display, parameter setting and automatic calibration. Finally, the system performance is tested. The results show ISFET differential current mode read circuit can effectively decrease the error, reduce power consumption, inhibit temperature drift,and have long service life.
