As nanostructured bioelectronic interfaces continue to evolve for sensor applications, new readout circuits are needed to harness their capabilities. This paper presents a single-chip amperometric readout circuit and electrode array system suitable for bioelectrochemical measurements. The chip features a CMOS potentiostat with high resolution, rangeprogrammable current readout and electrochemical cell potential drive circuitry, which can perform on-chip chronoamperometry and cyclic voltammetrydoi:10.1109/iscas.2007.378452 dblp:conf/iscas/MasonHYZ07 fatcat:dp7m2jmiaba7nbvv7vdwotnupe
