Draw the timing diagram for a SRAM Read. What happens if we delay the enabling of Clock signal?
1135Approximately, what were the sizes of your transistors in the SRAM cell? How did you arrive at those sizes?
1149Draw a transistor level two input NAND gate. Explain its sizing (a) considering Vth (b) for equal rise and fall times
1663You 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
1573What is Latch Up? Explain Latch Up with cross section of a CMOS Inverter. How do you avoid Latch Up?
1338How does the size of PMOS Pull Up transistors (for bit & bit- lines) affect SRAM's performance?
1206For 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)
1278Give the logic expression for an AOI gate. Draw its transistor level equivalent. Draw its stick diagram
1485Why do we gradually increase the size of inverters in buffer design? Why not give the output of a circuit to one large inverter?
