Abstract
Arrays of biosensors are provided along with methods for operating the arrays of biosensors. The array of biosensors may include a first reference electrode that is connected to an input of a first control amplifier; a first working electrode and a second working electrode in proximity with the first reference electrode; and a counter electrode that is connected to at least an output of the first control amplifier, where the first control amplifier is operative with the counter electrode to maintain a first specified voltage between the first working electrode and the first reference electrode, and between the second working electrode and the first reference electrode. The array of biosensors optionally may further include a second reference electrode that is connected to an input of a second control amplifier, where the second control amplifier is operative with the counter electrode to maintain a second specified voltage between the first working electrode and the second reference electrode, and between the second working electrode and the second reference electrode.
