    Some Sample  questions (m.tech.)  tech.--24, apti.--20

    1. On cmos power( formula- P=CV*Vf

    2. Lowest noise margin in which logic family--
      a) TTL   b)  CMOS   c)   biCMOS   d)    all have same                                    

    3. If CMOS has tr(rise time)=tf.find Wp/Wn. given beta(n)=2*beta(p)

    4. gm of a transistor is proportional to 
      a)Ic b)Vt c)1/Vt d)none

    5. If A and B are given in 2's complement find A-B in decimal.

    6. Set up time,hold time ,clock to Q delay time (very important)

    7. .3 questions on opamp (transfer function)(2 marks each)

    8. 2 questions on sequence detector (2 marks each)

    9. Logic function boolean expressions(true/false) (3 question-1 mark each)probabily all false
