write the two advantages and two disadvantages of discrete component in an electronic circuit
Answers
Answer:
An elementary electronic device constructed as a single unit. Before the advent of integrated circuits (chips), all transistors, resistors, capacitors and diodes were discrete. Discrete components are widely used in amplifiers and other electronic products that use large amounts of current.
Explanation:
The major advantages of integrated circuits over those made by interconnecting discrete components are as follows : Extremely small size – Thousands times smaller than discrete circuits. It is because of fabrication of various circuit elements in a single chip of semiconductor material.
Major disadvantages are:
•Assembling and wiring of all individual discrete components take more time and occupies a larger space required.
Replacement of a failed component is complicated in an existed circuit or system.
Actually, the elements are connected using soldering process so, that may have caused less reliability.
To overcome these problems of reliability and space conservation, integrated circuits are developed.
Explanation:
Advantage:-
------------------
1.The entire physical size of IC is extremely small than that of discrete circuit.
2.The weight of an IC is very less as compared entire discrete circuits.
3.It’s more reliable.Because of their smaller size it has lower power consumption.
4.It can easily replace but it can hardly repair, in case of failure.Because of an absence of parasitic and capacitance effect it has increased operating speed.Temperature differences between components of a circuit are small.
5.It has suitable for small signal operation.
has suitable for small signal operation.The reduction in power consumption is achieved due to extremely small size of IC.
Disadvantaged:-
------------------------
1.Coils or indicators cannot be fabricated.
2.It can be handle only limited amount of power.
3.High grade P-N-P assembly is not possible.
4.It is difficult to be achieved low temperature coefficient.
5.The power dissipation is limited to 10 watts.
6.Low noise and high voltage operation are not easily obtained.
7.Inductors and transformers are needed connecting to exterior to the semiconductor chip as it is not possible to fabricate inductor and transformers on the semiconductor chip surface.
8.Inductors cannot be fabricated directly.
9.Low noise and high voltage operation are not easily obtained.
