Abstract
A method 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 values. The impedance representative of the biosensor based upon the transformed time varying voltage signal and the time varying current signal is calculated.
