Impedance measurement device: a System-on-Chip implementation
MetadataShow full item record
This System-on-Chip implementation is aimed at measuring small impedance with high accuracy. This system consists of an Analog sensor, Analog to Digital converter and a computational unit that is used to calculate the magnitude and phase of the impedance. The SoC can find its application in affinity based biosensors that use impedance spectroscopy to determine the properties of the analyte. Other applications include measuring impedances from probes buried in building structures to monitor the health of he buildings.
