CMOS full form: Working Principles of CMOS
Complementary Metal-Oxide-Semiconductor (CMOS) technology is like a duo of efficient workers, each with a unique way of handling tasks. Imagine one worker (a transistor) loves to switch on the lights, and the other prefers turning them off. When they work together, they ensure the lights are managed flawlessly.
- The Duo: P-type and N-type Transistors
- P-type Transistors (The Light Switch-On Worker): These workers allow electrical current to flow when signaled, like turning on a light switch.
- N-type Transistors (The Light Switch-Off Worker): These workers block the flow of current when signaled, like turning off a light switch.
- Complementary Operation (The Light Management Team)
- Teamwork: By combining both types of workers (transistors), CMOS forms a powerful team. When one worker turns on the light, the other turns it off. This complementary action ensures efficient and precise management of electrical signals.
