CMOS: The King of Low Power
CMOS circuits have revolutionized power efficiency in digital electronics. They consume negligible power when static and offer exceptional efficiency in dynamic operation, making them indispensable in modern portable devices.
TTL’s Trade-Off Between Speed and Power
TTL’s fast switching comes at the cost of higher power consumption. While suitable for high-speed operations, TTL logic may not be the best for battery-powered applications.
Noise Immunity and Signal Integrity
CMOS: High Noise Immunity
However, CMOS logic’s symmetric design provides inherent noise immunity, allowing it to resist external interference and maintain signal integrity even in challenging environments.
TTL’s Signal Integrity Challenges
TTL circuits are more susceptible to noise due to their single-ended output configurations. Also, Proper shielding and signal conditioning are often required to maintain signal integrity.
