WebMar 25, 2009 · So I'm starting to think that MOSFETs that had different channel lengths, but were otherwise identical would have the same saturation current, regardless of channel length (although Vds required for saturation would be different since that does depend on channel length). WebFundamentals of MOSFET and IGBT Gate Driver Circuits The popularity and proliferation of MOSFET technology for digital and power applications is driven by two of their major advantages over the bipolar junction transistors. One of these benefits is the ease of use of the MOSFET devices in high frequency switching applications.

Classical drain current equations for MOS transistors For long-channel MOS transistors (L = 10 Pm), the drain current saturation is related to pinchoff (Hofstein & Heiman, 1963). A qualitative discussion of MOS transistor operation is WebDrain induced barrier lowering or DIBL is a secondary effect in MOSFETs referring originally to a reduction of threshold voltage of the transistor at higher drain voltages. The origin of the threshold decrease can be understood as a consequence of charge neutrality: the Yau charge-sharing model.
