ee.sharif.eduB. Subthreshold Leakage Subthreshold or weak inversion conduction current be-tween source and drain in an MOS transistor occurs when gate voltage is below [15]. The weak inversion region is seen in Fig. 1 as the linear region of the curve (semilog plot). In the weak inversion, the minority carrier concentration is

Perrott Comparison of Strong and Weak Inversion for g m Assumption: I d is constant with only W varying Strong inversion formulation predicts ever increasing g m with reduced overdrive voltage-Reduced current density leads to reduced overdrive voltage and therefore higher g m Weak inversion formulation predicts that g m will hit a maximum value as current density is reduced
