Ion sensitive field effect transistor(ISFET)devices are highly accurate,convenient,fast and low-cost in the detection of ions and biological macromolecules,such as DNA molecules,antibodies,enzymatic substrates and cel...
This paper presents a high precision CMOS opamp suitable for ISFET readout. The opamp is tailored to provide a constant bias condition for ISFET as part of the readout circuits and,hence,is compatible for single chip ...
