An ion sensitive field-effect transistor (ISFET) integrated with a low-power pH sensor 4

2. pH response speed: ISFET has a slower response speed, which can be improved by selecting appropriate ion sensitive layer materials and optimizing structural design.diode

3. Manufacturing process: The manufacturing process of ISFET requires high-precision manufacturing equipment and process control, and requires process optimization and strict quality control.diode

Conclusion:

This article introduces the design of an ISFET integrated with a low-power pH sensor. By using ISFET as an ion sensitive element, a pH sensor with smaller size, low power consumption, and high integration can be achieved. The design includes the manufacturing of ISFETs, the design of signal conditioning circuits, data processing and interface design, as well as optimization and testing. At the same time, common problems and solutions were also introduced, such as temperature compensation, pH response speed, and manufacturing processes. This design can be applied in fields such as environmental monitoring, biomedicine, and food safety, and has broad application prospects.diode
