title = "Effect of mobile ionic-charge on CMOS based Ion-Sensitive Field-Effect Transistors (ISFETs)",
abstract = "This work is an investigation on the large threshold voltage variation exhibited in CMOS based ISFETs. This irregularity is thoroughly examined and is identified to be caused by mobile ionic charge that is induced in the sensing membrane when the membrane is in contact with the ionic-solution. This auxiliary charge increments the effective capacitance of the sensing membrane, causing irregular shifts in the characteristics of the devices. Several methods for overcoming this issue are addressed.",
