The new circuit design in CID 3.0 has lower power consumption because it has fewer components, and it affords better accuracy through the modification of the analog part of CID 2.0 and the use of oversampling. This approach successfully afforded CID 3.0 with higher measurement stability for evaluating a high-performance coating with impedance values exceeding $10^{9}~\Omega $. Furthermore, CID 3.0 could detect impedance decreases associated with coating delamination when the coating suffers an attack. © 2013 IEEE.Coating degradation; Corrosion monitor; Electrochemical impedance spectroscopy; Field-programmable gate array; OversamplingCorrosion resistant coatings; Electrochemical corrosion; Electrochemical impedance spectroscopy; Circuit designs; Coating degradation; Coating delamination; Corrosion monitor; Electrochemical-impedance spectroscopies; High performance coatings; Impedance detectors; Low-power consumption; Lower-power consumption; Over sampling; Field programmable gate arrays (FPGA)journal article10.1109/ACCESS.2022.31511002-s2.0-85124734177
