Circuit Diagram Full Adder Using Cmos

By | September 3, 2017



Do you want to know how a full adder using CMOS works? Circuit diagrams can be intimidating, but once you understand the basics, they're a great tool for expanding your understanding of electronics.

A full adder is a digital circuit that can add two bit numbers and also account for a carry from a previous addition. It operates on what’s called a half-adder, which you can think of as two interconnected gates. The full adder adds a third input, known as the “carry in” and outputs two signals, the “sum” and “carry out.”

CMOS (complementary metal–oxide–semiconductor) is one of the most commonly used logic families today. It’s easy to use, highly versatile, and is one of the most cost-effective solutions available. CMOS technology is widely used for full adders as it offers good performance, consuming less power and having a smaller footprint.

Constructing a CMOS full adder is not an easy task though. You need to be aware of different components and know how to configure them. Let’s take a look at a typical circuit diagram for a CMOS full adder and explore its different components.

The heart of this circuit is formed by two MOSFETs, both n-type and p-type. These are connected to the two inputs, A and B, and the carry-in, C-in, respectively. The output, SUM, is generated from the XOR gate, while the C-out is generated from the AND gate. The pull-up resistor is a vital part of the circuit, as it ensures that the output signals remain constant, even when no input signals are applied.

Understanding the functioning of a full adder with CMOS can help you gain an insight into the design and construction of digital systems. With detailed circuit diagrams and well-defined instructions, such as those found in our blog, you can easily build your own full adder using CMOS.
