Active Circuit Modeling of Experimental OSCC Bio-Impedance Data Employing Four Terminal Floating Nullor

Year: 2026

Type: article

Abstract: A novel design procedure to model experimental bio-impedance data of oral squamous cell carcinoma (OSCC) is introduced using a four-terminal floating nullor (FTFN). The bio-impedance generation using an active block may contribute an additional option to study and analyze the behavior of OSCC by utilizing the single dispersion Cole model (SDCM) without any physical measurement in the future. The model parameters are extracted using the non-linear least squares method in MATLAB with minimum error %. To model the experimental data of the cancer bio-impedance in the range 20 Hz–5 MHz, two resistors, one fractional capacitor, and FTFN are involved to design the Cole model. The proposed design may be a pioneering step in the design of a circuit that depicts practical data for OSCC. The workability of the design is verified with simulation results, and it follows the experimental OSCC data.
