Which is the best description of an integrated circuit?
An integrated circuit consists of capacitors, resistors, transistors, and other metallic connections required for a complete electrical circuit. The most popular electrical circuits are the MOSFET circuits because the switching time can be easily reduced. In addition, the transistors switch faster if the devices are made smaller.
How are application specific integrated circuits ( ICs ) classified?
The ICs can also be classified based on their usage model and availability in the market. Application-specific integrated circuits (ASIC) represent a class of ICs, which contain customized functionalities, such as signal processing or security functions, and meet specific performance targets that are not readily available in the market.
Why are switched capacitor resistors used in integrated circuits?
The Switched Capacitor resistor is often used as a replacement for simple resistors in integrated circuits because it is easier to fabricate reliably with a wide range of values. It also has the benefit that the equivalent resistor value can be adjusted by changing the switching frequency.
Why did the number of integrated circuits increase?
Due to the improvement of the technology in building integrated circuits, primarily due to the decrease in the individual devices as well as in the increase in the area of the circuit, there has been a rapid growth in the number of transistors on an integrated circuit since the first such circuit was fabricated in 1961 with only four transistors.
An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or “chip”) of semiconductor material, usually silicon.
What are the advantages of ICs over discrete circuits?
ICs have two main advantages over discrete circuits : cost and performance. Cost is low because the chips, with all their components, are printed as a unit by photolithography rather than being constructed one transistor at a time. Furthermore, packaged ICs use much less material than discrete circuits.
Who was the first person to invent the integrated circuit?
Kilby won the 2000 Nobel Prize in Physics for his part in the invention of the integrated circuit. His work was named an IEEE Milestone in 2009.
What are the benefits of digital integrated circuits?
Digital integrated circuits can contain anywhere from one to billions of logic gates, flip-flops, multiplexers, and other circuits in a few square millimeters. The small size of these circuits allows high speed, low power dissipation, and reduced manufacturing cost compared with board-level integration.
