By leveraging the fundamental principles of CMOS design, engineers can create circuits that are low power, highly efficient, and scalable.
Detailed Explanation
CMOS design principles focus on creating circuits that consume less power and are more efficient compared to other technologies. Scalability refers to the ability to design larger and more complex circuits without a significant increase in cost or energy consumption. This is critical in modern electronics because device performance is often improved without needing larger batteries or more energy.
Examples & Analogies
Imagine you are running a marathon. If you can pace yourself well, you can conserve energy and perform better over a longer distance. Similarly, CMOS circuits are designed to manage energy efficiently, which allows devices to run longer and perform better.
