Question { Infosys, 6152 }

Explain why & how a MOSFET works?

Answer

By applying the gate voltage we can create a channel b/w source and drain. thereafter by increasing the Vds, the current Id flow from source to drain. Depending upon gate voltage Vg we can manipulate the width of the channel b/w Source and Drain. it will reflect on Id current variation.

Question { Infosys, 12686 }

How does Resistance of the metal lines vary with increasing
thickness and increasing length?

Answer

R= L/W * Rs Where,

R= resistance
L= length
W= width
Rs= Sheet resistance
