MOSFET saturation: I_D = (K/2)·(V_GS - V_T)²

Layer 1 — Physicsin the engineering-physics subtree

The MOSFET saturation-region drain current follows the 'square-law' model: I_D = (K/2)·(V_GS - V_T)², where K = μ_n·C_ox·W/L (μ_n electron mobility, C_ox oxide capacitance per unit area, W/L channel width-to-length ratio) is the…
