ENGLISH SOLUTION
==================================================
Question:
Which of the following is correct regarding
figure of merit of an IC?
--------------------------------------------------
Concept
--------------------------------------------------
The figure of merit of a digital IC is defined as:
Figure of Merit
= Propagation Delay Time × Power Dissipation
It is also known as the:
Speed-Power Product
A lower value indicates a better IC because
it provides high speed with low power consumption.
--------------------------------------------------
Therefore
--------------------------------------------------
Correct relation:
Propagation delay time × power
--------------------------------------------------
Final Answer
--------------------------------------------------
Correct Option: C
