VLSI Interview questions - CISCO

1) Some star to delta conversion networks for finding the R

2) What shud we do to reduce latch up -----

3) How to reduce short channel effects – substrate is to heavily doped

4) Some mental ability q’s

5) Convert a mux to an OR gate

6) Design a 2X1 mux using half adders

7) Some clk skew q

8) Some simple ckt which has 2 voltage sources in series to it and a current source u had

to find the I through resistor which is a easy one to solve

9) Two latches constructed using muxes are cascaded such that it acts like a master slave

flipflop and u shud mention wether it is +ve edge triggered or –ve edge triggered..

10) Some stuck at fault in a ckt and u shud mention the test vector for it.

11) Some k map simplification….

12) Given a boolean eq. and u shud design the ckt using min no. of nmos and pmos for

that go for pseudo nmos technique.
