A modified voltage-clamped ISFET readout circuit for low voltage applications
© 2017 IEEE. This paper present an ISFET readout circuit which is operated at 0.8 V supply and senses pH on both current and voltage accurately. This readout circuit requires one gate-source voltage and two drain-source voltage to operate in the weak inversion region. The power consumption at pH 7 i...

This paper present an ISFET readout circuit which is operated at 0.8 V supply and senses pH on both current and voltage accurately. This readout circuit requires one gate-source voltage and two drain-source voltage to operate in the weak inversion region. The power consumption at pH 7 is 2.5 nW. The output voltage of this readout circuit tracks with pH linearly while its current output is the exponential function to pH.
