PROCESSING TECHNIQUE FOR AN IMPEDANCE BIOSENSOR

摘要

A system for determining impedance includes receiving a time varying voltage signal from a biosensor and receiving a time varying current signal from the biosensor. The time varying voltage signal and the time varying current signal are transformed to a domain that represents complex impedance values. Calculating parameters based upon the impedance values in a manner suitable to automatically select a first endpoint of an analysis aperture in a region of interest.
