Answer / ahamed.s
Due ot decrease in Channel length at pinch off voltage five
factors deviate
1)Threshold variation
2)Mobility degration due to Vertical field
3)Velocity Saturation
4)Hot carrier effects
5)O/p impedence variations with drain source voltage

Answer / k s rao
short channel effets is one of the effect in advanced mos
modelang there three short channel effects sub threshold
operation and leckeg currents,
short channel effects degrads the operation of the mos
transistor due to the following factors
large electric feilds
raduced out impedance
hot carrier effect

Have you studied buses? What types?
Explain various adders and diff between them?
You have three adjacent parallel metal lines. Two out of phase signals pass through the outer two metal lines. Draw the waveforms in the centre metal line due to interference. Now, draw the signals if the signals in outer metal lines are in phase with each other
