CMOS technology uses complementary metal oxide semiconductors and comes in three types: PMOS, NMOS, and HMOS. It allows for low power dissipation and high density circuits. While bipolar and CMOS structures were converging, CMOS and BICMOS technologies were used for applications requiring very low power such as watches, calculators, and pacemakers. Today, low power design is important for VLSI and gigascale integration due to increasing concerns about power consumption without compromising performance. CMOS enables low power design through devices like MOSFETs.

CMOS stands for Complementary Metal-Oxide-Semiconductor, and it refers to a semiconductor technology
In a CMOS circuit:
Metal: Represents the conductive material used in the transistor gates.
Oxide: Refers to the insulating material, typically silicon dioxide, which separates the gate from the semiconductor.
Semiconductor: The underlying silicon substrate that acts as the channel through which current flows.
IN COMPUTER ENGINEERING, A LOGIC FAMILY MAY REFER TO ONE OF TWO RELATED CONCEPTS. A "LOGIC FAMILY" MAY ALSO REFER TO A SET OF TECHNIQUES USED TO IMPLEMENT LOGIC WITHIN VLSI INTEGRATED CIRCUITS SUCH AS CENTRAL PROCESSORS, MEMORIES, OR OTHER COMPLEX FUNCTIONS. THE MOST COMMON LOGIC FAMILY IN MODERN SEMICONDUCTOR DEVICES IS METAL–OXIDE–SEMICONDUCTOR (MOS) LOGIC, DUE TO LOW POWER CONSUMPTION, SMALL TRANSISTOR SIZES, AND HIGH TRANSISTOR DENSITY.
NEW DESIGN METHODOLOGIES FOR HIGH-SPEED MIXED-MODE CMOS FULL ADDER CIRCUITSVLSICS Design
This paper presents the design of high-speed full adder circuits using a new CMOS mixed mode logic family. The objective of this work is to present a new full adder design circuits combined with current mode circuit in one unit to implement a full adder cell. This paper also discusses a high- speed hybrid majority function based 1-bit full adder that uses MOS capacitors (MOSCAP) in its structure with conventional static and dynamic CMOS logic circuit. The static Majority function (bridge) design style enjoys a high degree of regularity and symmetric higher density than the conventional CMOS design style as well as lower power consumption by using bridge transistors. This technique helps in reducing power consumption, propagation delay, and area of digital circuits while maintaining low complexity of mixedmode logic designs. Dynamic CMOS circuits enjoy area, delay and testability advantages over static CMOS circuits. Simulation results illustrate the superiority of the new designed adder circuits against the reported conventional CMOS, dynamic and majority function adder circuits, in terms of power, delay, power delay product (PDP) and energy delay product (EDP). The design is implemented on UMC 0.18µm process models in Cadence Virtuoso Schematic Composer at 1.8 V single ended supply voltage and simulations are carried out on Spectre S.
