A pH sensor is a commonly used chemical sensor that can measure the acidity or alkalinity of a solution
The structure of ISFET is similar to a standard MOSFET, consisting of a gate,
Design a suitable signal conditioning circuit to process the output signal of ISFET and convert it into a readable voltage or current signal.
pH response speed: ISFET has a slower response speed
As one of the basic components of electronic devices
In the amplification effect of transistors, the base emitter voltage (VBE) remains almost constant,
