In this work, a low power optimized circuit based on 3D Cylindrical (Cyl) Gate All Around (GAA) Tunnel Field Effect Transistor (TFET) will propose for low power circuit applications using TCAD Synopsys and EDA tool. The proposed device initially optimize and examine for DC/Analog characteristics such as OFF current (IOFF), ON current (ION), sub-threshold swing (SS), transconductance (gm), Cut-off frequency (ft), etc. Further, the optimized device performances is investigated for entire range of bias voltage using LUT (look up table) approach with trap charge investigation for reliability analysis and produce a Spice equivalent model using Verilog-A based on the proposed device. Further, the proposed Spice equivalent model used for the implementation of COVID-19 Circuit Applications. The examined biosensor circuit circuit based on the proposed low power device such as TFET minimize the leakage current without deteriorate the switching speed of the device due to low power tunnel transistors based on hetero-dielectric and spacer engineering.
