What are the different types of skews used in vlsi?
In what cases do you need to double clock a signal before presenting it to a synchronous state machine?
What transistor level design tools are you proficient with? What types of designs were they used on?
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
Tell me how BJT works.
What are set up time & hold time constraints? What do they signify?
How does Resistance of the metal lines vary with increasing thickness and increasing length?
Explain the operation considering a two processor computer system with a cache for each processor.
Explain Custom Design Flow?
Draw Vds-Ids curve for a MOSFET. Now, show how this curve changes with increasing Vgs.
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?
Draw Vds-Ids curve for a MOSFET. Now, show how this curve changes with increasing transistor width.
Explain how logical gates are controlled by Boolean logic?
