Draw the stick diagram of a NOR gate. Optimize it

1228

Given a layout, draw its transistor level circuit. (I was given a 3 input AND gate and a 2 input Multiplexer. You can expect any simple 2 or 3 input gates)

1158

Draw the timing diagram for a SRAM Read. What happens if we delay the enabling of Clock signal?

1087

Draw Vds-Ids curve for a MOSFET. Now, show how this curve changes with increasing Vgs.

1059

Approximately, what were the sizes of your transistors in the SRAM cell? How did you arrive at those sizes?

1093

Draw a 6-T SRAM Cell and explain the Read and Write operations

1234

Draw a transistor level two input NAND gate. Explain its sizing (a) considering Vth (b) for equal rise and fall times

1593

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
