Question

Which of the following is not a type of an IC?
A. Analog IC
B. Digital IC
C. Mixed IC
D. Compound IC

Answer 1

IC is an abbreviation of Integrated Circuit. IC’s can work on both analog and digital inputs and thus they are distinguished as the name suggests. Verify every option to check which one of the options is not the IC.

Complete answer:
We know that an Integrated Circuit (IC) is the fabrication of an entire circuit consisting of passive components like resistor, capacitor or the active devices like diodes and transistors on a single block. It has very small dimensions and still works more effectively than the analog circuit.To answer this question, let us verify each option as follows,

Analog IC: It is a type of IC in which the output of IC’s processes the analog signal which changes continuously from the minimum to the maximum. Therefore, we can say the output of Analog IC does vary in accordance with the analog input.
Digital IC: We know that the digital IC’s have only two states of output. That is either high or low. Digital IC’s are fabricated by the use of logic gates.
Mixed IC: It is a type of Integrated Circuit in which the analog IC and Digital IC’s are fabricated on the single semiconductor device so that the circuit can work on both Digital and analog input. Therefore, digital IC, analog IC and mixed IC are the types of IC’s and thus, we can say, the compound IC is not the type of IC.

So, the correct answer is option D.

Note: IC’s can hold millions of passive components like resistor and capacitors and still bear a very small size. The computers in the late sixties used to be the size of a room. With the help of IC’s, the modern computers are able to fit into the pocket.
