Questions Related to integrated chips

Production of ICs is preferred in industrial scales because:

physics semiconductors integrated circuits & microprocessor integrated chips semiconductor devices

  1. it reduces the cost of production.

  2. it makes the task of fabrication of a circuit easier.

  3. it improves the efficiency of the circuit.

  4. specifications of a circuit is same for all applications.

Show answer
Correct Option: A
Explanation:

Integrated circuits are electronic circuits formed on a small piece of semiconducting material, which perform the same function as a larger circuit made from discrete components. They are compact, and cheap and fast and more efficient than conventional circuits. Due to their low cost of production on large scales they are produced on industrial scale.

Which of the following is an advantage of a conventional circuit over integrated circuit?

physics semiconductors integrated circuits & microprocessor integrated chips semiconductor devices

  1. They are fast.

  2. They have higher power handling capability.

  3. They are large in size.

  4. All of the above.

Show answer
Correct Option: B
Explanation:

Integrated circuits are electronic circuits formed on a small piece of semiconducting material, which perform the same function as a larger circuit made from discrete components. They are compact, and cheap and fast and more efficient than conventional circuits, and hence they are preferred over them. However conventional circuits still have the advantage of high power handling capacity over the ICs.

Choose the correct statements:

physics semiconductors integrated circuits & microprocessor integrated chips semiconductor devices

  1. It is easier to fabricate $10000$ AND gates using circuit components than on an integrated chip.

  2. It is easier to fabricate $10000$ AND gates on an integrated chip than fabricating them using circuit components.

  3. It is easier to fabricate a single AND gate using circuit components as compared to on an IC.

  4. It is easier to fabricate a single AND gate on an IC as compared to using circuit components.

Show answer
Correct Option: B,C
Explanation:

Integrated chips have advantage when being used to fabricate a number of components at the same time. However when single component is being fabricated, it is advisable to fabricate components using circuit components instead of an Integrated Circuit.

Choose the correct statement:

physics semiconductors integrated circuits & microprocessor integrated chips semiconductor devices

  1. Integrated circuits are less efficient in performance at all voltages.

  2. Integrated circuits are more efficient in performance at low voltages.

  3. Integrated circuits are less efficient in performance at high voltages.

  4. Performance of an integrated circuit is independent of the magnitude of applied voltage.

Show answer
Correct Option: B
Explanation:

Integrated circuits are used for low voltage applications. They are low power devices for use in application like microprocessor chips. 
For high voltage devices like transformers, conventional circuits are used.
