WebNov 22, 2015 · Weak or strong inversion modes are operation modes of MOSFETs which differ in channel current density. Weak inversion mode is also called subthreshold mode of operation. Velocity saturation of the majority charge carriers in the channel increases with increasing inversion, means in weak inversion operation there's no velocity saturation ... Webincreasing but rather gradually. Therefore, we define three regions of channel inversion with respect to VGS. The first region is weak inversion that occurs when VGS is much below …

Web6.3 is formed between the substrate and the induced channel. The MOSFET operated in this region is said to be in weak inversion or the subthreshold region because the surface under the oxide is not heavily n+.
