An auto-offset-removal circuit for chemical sensing based on the PG-ISFET

This paper presents a novel readout circuit for a pH sensitive programmable-gate ion-sensitive field effect transistor (PG-ISFET) to overcome bias issues due to threshold voltage variation and increase output-referred sensitivity. Compared to other commonly-used ISFET readouts, this circuit uses two...
