Abstract
A potentiostat is provided for a biosensor circuit and permits sequential and simultaneous measurements to be performed at different cells across a matrix of biosensing devices. Accordingly, a potentiostat comprises a first differential amplifier for receiving a scanning voltage at a first input terminal and a voltage at the reference electrode at a second input terminal and for generating an output voltage at an output terminal to be applied to the working electrode, wherein, when in use, a feedback loop of the potentiostat circuit is closed between the reference electrode and the working electrode.
