If we design every transistor like a simple switch that is operated through input voltage (Vin), then operations of the inverter can be observed very simply: ZKSElectronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Product CMOS Inverter Operation & Working Once the input voltage of CMOS changes between 0 to 5 volts, then both the transistors state will be changed accordingly. It is very significant to observe that the CMOS device does not have any resistors, so it will be more power-efficient. ZKSElectronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Product Input voltage (Vin) is connected to both the gate terminals of transistors & output voltage (Vout) is connected to the drain (D) terminals of the transistor. The NMOS transistor is connected at the drain (D) & gate (G) terminals, a voltage supply (VDD) is connected at the source terminal of PMOS & a GND terminal is connected at the source terminal of NMOS. The connection of both the PMOS & NMOS transistors in the CMOS inverter can be done like this. The general CMOS inverter structure is the combination of both the PMOS & NMOS transistors where the pMOS is arranged at the top & nMOS is arranged at the bottom. The CMOS inverter circuit diagram is shown below.

The CMOS inverter truth table is shown above. In digital logic circuits, binary arithmetic & switching or logic function’s mathematical manipulation are best performed through the symbols 0 & 1. The logic element like an inverter reverses the applied input signal.

A CMOS inverter is a FET (field effect transistor), composed of a metal gate that lies on top of oxygen’s insulating layer on top of a semiconductor. ZKSElectronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Product What is CMOS Inverter?ĬMOS inverter definition is a device that is used to generate logic functions is known as CMOS inverter and is the essential component in all integrated circuits. This article discusses an overview of the CMOS inverter and its working with applications. So, a CMOS inverter is a very simple circuit, designed with two opposite-polarity MOSFETs within a complementary way.


A basic inverter circuit is used to accomplish a logic variable by complementing from A to A’. The inverter is accepted universally as the basic logic gate while performing a Boolean operation on a single i/p variable. The main CMOS devices characteristics are consumption of low static power & high noise immunity. CMOS is a type of MOSFET, where its fabrication process uses complementary & symmetrical P-type & N-type MOSFET pairs for logic functions. The term “CMOS” stands for “complementary-symmetry metal–oxide–semiconductor” which is pronounced as “see mos”.
