VLSI Design Question Bank EC6601 Regulation 2013 Anna University free download. EC6601 Question Bank pdf file download VLSI Design Question Bank.

Sample VLSI Design Question Bank:

1.How path can be implemented in VLSI system?

A data path is best implemented in a bit –sliced fashion. A single layout is used respectively for every bit in the data word. This regular approach eases the design effort and results in fast and dense layouts.

2.Comment on performance of ripple carry adder.

A ripple carry adder has a performance that is linearly proportional to the number of bits. Circuit optimizations concentrate on reducing the delay of the carry path. A number of circuit topologies exist providing that careful optimization of the circuit topology and the transistor
sizes helps to reduce the capacitance on the carry bit.

3.What is the logic of adder for increasing its performance ?

Other adder structures use logic optimizations to increase the performance (carry bypass, carry select, carry lookahead). Performance increase comes at the cost area.

4.What is multiplier circuit ?

A multiplier is nothing more than a collection of cascaded adders. Critical path is far more complex and optimizations are different compared to adders.

5.Which factors dominate the performance of programmable shifter ?

The performance and the area of a programmable shifter are dominated by the wiring.

6.What is meant by data path ?

A datapath is a functional units, such as arithmetic logic units or multipliers, that perform data processing operations, registers and buses. Along with the control unit it composes the central processing unit.

EE6603 Question Bank Power System Operation and Control

EE6603 Question Bank Power System Operation and Control Regulation 2013 Anna University free download. Power System Operation and Control Question Bank free pdf.

Sample EE6603 Question Bank:

1. What is the major control loops used in large generators?

The major control loops used in large generators are
1. Automatic voltage regulator (AVR)
2. Automatic load frequency control (ALFC).

2. What is the use of secondary loop?

A slower secondary loop maintains the fine adjustment of the frequency, and also by reset action maintains proper MW interchange with other pool members. This loop is insensitive to rapid load and frequency changes but focuses instead on drift like changes which take place over periods of minutes.

3. What is the adv of AVR loop over ALFC?

AVR loop is much faster than the ALFC loop and therefore there is a tendency, for the VR dynamics to settle down before they can make themselves felt in the slower load frequency control channel.

4. What is the diff. between large and small signal analysis?

Large signal analysis is used where voltage and power may undergo sudden changes of magnitude that may approach 100 percent of operating values. Usually this type of analysis leads to differential equations of non-linear type. Small signal anaysis is used when variable excursions are relatively small, typically at most a few percent of normal operating values.

5. What is the exciter?

The exciter is the main component in AVR loop. It delivers the DC power to the generator field. It must have adequate power capacity and sufficient speed of response (rise time less than 0.1 sec).

6. What is the function of AVR?

The basic role of the AVR is to provide constancy of the generator terminal voltage during normal, small and slow changes in the load.
