Effect of threshold voltage on width
WebWithout halo doping, threshold voltage decreases with gate length, as the source/drain junction lateral field penetrates into the channel, raising the surface potential. As a result, less gate voltage is required for the surface potential to reach the same threshold value. WebNov 24, 2011 · The circuit performance can be improved by increasing channel width of transistors in critical path and decreasing channel width for sleep transistor resulting in high threshold voltage. This reduces sub threshold, short circuit and leakage currents. Simulations have been carried out using Cadence Virtuoso Spectre simulator with …

The threshold voltage, commonly abbreviated as Vth or VGS(th), of a field-effect transistor (FET) is the minimum gate-to-source voltage (VGS) that is needed to create a conducting path between the source and drain terminals. It is an important scaling factor to maintain power efficiency. When referring to a junction field-effect transistor (JFET), the threshold voltage is often called pinch-off voltage instead.
