This study designs a low-voltage, label-free and fully integrated impedance-based biosensor using standard complementary metal oxide semiconductor (CMOS) technology to compute both capacitance and resistance of the electrode-electrolyte interface. The proposed biosensor circuit is composed of a comm...
