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

1147

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

1285

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

1656

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

1332

Draw a CMOS Inverter. Explain its transfer characteristics

1181

How does the size of PMOS Pull Up transistors (for bit & bit- lines) affect SRAM's performance?

1204

For an AND-OR implementation of a two input Mux, how do you test for Stuck-At-0 and Stuck-At-1 faults at the internal nodes? (You can expect a circuit with some redundant logic)

1275

1266

Draw the SRAM Write Circuitry

1186

Give the logic expression for an AOI gate. Draw its transistor level equivalent. Draw its stick diagram

1472

Why do we gradually increase the size of inverters in buffer design? Why not give the output of a circuit to one large inverter?

1290

For a NMOS transistor acting as a pass transistor, say the gate is connected to VDD, give the output for a square pulse input going from 0 to VDD

1447
