In the design of a large inverter, why do we prefer to connect small transistors in parallel (thus increasing effective width) rather than lay out one transistor with large width?
1253Given 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)
1259Approximately, what were the sizes of your transistors in the SRAM cell? How did you arrive at those sizes?
1208Draw a transistor level two input NAND gate. Explain its sizing (a) considering Vth (b) for equal rise and fall times
1722How does the size of PMOS Pull Up transistors (for bit & bit- lines) affect SRAM's performance?
1256Give the logic expression for an AOI gate. Draw its transistor level equivalent. Draw its stick diagram
1555For 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
1510Draw Vds-Ids curve for a MOSFET. Now, show how this curve changes with increasing transistor width.
