Working of CMOS Inverter
- Input High (Logic 1): An NMOS transistor is turned on by input of high voltage (logic 1) while a PMOS transistor is turned off there. When these two things happen, the output voltage (logic 0) is lowered through reduced resistance path between an output terminal and ground.
- Input Low (Logic 0): In contrast, when a low voltage (logic 0) is provided to the input terminal, the NMOS transistor switches off and the PMOS transistor conducts. The output voltage (logic 1) rises as a result of the low resistance path that exists between the output terminal and the positive power supply voltage (VDD).
- The CMOS inverter operates more easily because of the complimentary characteristics of the NMOS and PMOS transistors. Because one of the transistors conducts while the other is off depending on the input voltage, the output of the transistors is inverted with respect to the input signal.
- CMOS inverters offer very low static power dissipation (no DC current flows between VDD and ground while the input is at a constant logic level) as a result of this complimentary pairing.
CMOS Inverter
The CMOS inverter is crucial in electronics, employed in memory chips and microprocessors among others. It generates complementary outputs whenever there are input signals through it. These inverters allow flexibility among circuit designers because they can be classified into many categories depending on their abilities and arrangements.
For their functionality, NMOS and PMOS transistors should counteract each other whereby they may react to input voltages by oscillating between conductive and non-conductive modes. Silicon substrates are host to connecting metal layers, transistors, and resistors in CMOS inverter components.
