Abstract
AbstractThis study's objectives are to deliver a relative analysis of non‐uniformly doped (NUD) and uniformly doped Dual Metal High‐K Schottky nanowire FET (DM‐HK‐SNWFET). Surface potential, subthreshold current, subthreshold swing, and drain current have been expressed and analyzed by resolving 2D Poisson's equation with suitable boundary conditions. The analog performance of the device is verified by examining cut‐off frequency (fT), trans‐conductance frequency product (TFP), gain frequency product (GFP), and gain trans‐conductance frequency product (GTFP). The results show suitable RF circuit parameters with a high switching ratio (≈3 × 109) and low subthreshold swing (61 mV/decade) for NUD‐DM‐HK‐SNWFET. Additionally, linearity frequency of merits (FOMs) and distortion performance are also studied by numerically calculating higher order voltage and current intercept point (VIP2, VIP3, IIP3, IMD3); 1‐dB compression point and Harmonics distortions (HD2 and HD3) using transconductance (gm1) along with its higher derivatives gm2 and gm3. These parameters exhibit high‐level linearity and low‐level distortion at zero crossover points in NUD‐DM‐HK‐SNWFET, making it a better contender for low‐power and high‐performance applications.
