Components of CMOS Inverter
- NMOS Transistor: An NMOS transistor consists of a gate, source, and drain terminals that make it an N-channel metal-oxide-semiconductor transistor. When the gate terminal is connected positively to the source terminal, an NMOS transistor conducts.
- PMOS Transistor: A P-channel metal-oxide-semiconductor transistor which has (the) gate, source and drain terminals similar to those of (its) counterpart (an) NMOS transistor. Commonly referred to, (some) PMOS transistor conducts when a negative voltage.
- Substrate: Silicon is used in building the PMOS as well as NMOS transistors. It ensures that they are both mechanically stable and electrically isolated.
- Interconnects: To create the required circuit configuration, the various transistor terminals are connected via interconnecting metal layers. Within the CMOS inverter, these metal layers guarantee appropriate signal routing and electrical connectivity.
- Gate Connection: The gate of the PMOS and NMOS transistors is connected to the input terminal of the CMOS inverter.
- Power Supply Connections: PMOS and NMOS transistors are usually attached to different points on the power supply devices. Whereas PMOS transistors are normally attached to a positive power supply voltage, known as VDD, NMOS transistors often use ground (0 volts).
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.
