CMOS A CMOS (Complementary Metal-Oxide Semiconductor) is a technology for constricting integrated circuits, which is used in microprocessors, microcontrollers and Static RAM, image sensors and data converters. CMOS are constructed in a way that all PMOS transistors are constructed in a way that all PMOS transistors must have either an input from the voltage source or from another PMOS transistor and the composition of a PMOS transistor creates low resistance between its source and drain contacts

Chipsets A chipset is a set of electronic components in an integrated circuit that manages the data flow between the processor, memory and peripherals. It is usually found in the motherboard of a computer. Chipsets are usually designed to work with a specific family of microprocessors. Because it controls communications between the processor and external devices, the chipset plays a crucial role in determining system performance. The chipset normally consists of two major microchips. These

Without the algorithm, the energy is consumed by seven operations/blocks: DAC switching, DAC reset, SAR control logic, comparator and memory. It can be seen that without memory, every part consume less power. Moreover, in the prototype chip, all the circuits are powered by 3.3V supply, so the digital components used a large portion of energy in both the two cases. If fabricated by an advanced

to punched card machines, and then to stored-program computers. The history of stored-program computers relates first to computer architecture, that is, the organization of the units to perform input and output, to store data and to operate as an integrated mechanism. Before the development of the general-purpose computer, most calculations were done by humans. Mechanical tools to help humans with digital calculations were then called "calculating machines", by proprietary names, or even as they are

Nanotechnology in Electronics: The application of nanotechnology can be very well extended to the field of electronics. This nanotechnology gives a promising technology when this is combined with conventional approach in electronics. The main advantage of nano electronics is increasing the capabilities of electronic devices. The screen displays on electronic devices can be effectively improved by applying the nanotechnology. This approach considerably reduces the power consumption and also reducing

your motherboard. There are two major types of motherboards: integrated and nonintegrated. On a nonintegrated system board each major assembly is installed in the computer as an expansion card (Doctor, Dulaney, & Skandier, 2007). This includes video cards, disk controllers, and other accessories. On an integrated system board most of the components are integrated into the motherboard circuitry. Most motherboards now a day are integrated. These boards were designed for simplicity. You don’t have
