10.5 Integrated Circuits IC

An integrated circuit d882m 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. However, it is important to keep in check the power dissipated by a transistor so that the amount of heat produced in an integrated circuit can be kept under control.

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.

At present, a typical integrated circuit has about 80 million transistors. The single d882m most important criterion is to keep in check the enormous heat produced by such circuits.

The ICs or chips used in a PCB do various tasks, such as signal acquisition, transformation, processing, and transfer. Some of these chips (for example, an encryption or image compression chip) work on digital signals and are called digital ICs, whereas others work on analog or both types of signals, and called analog/mixed-signal (AMS) chips.

Examples of the latter type include voltage regulators, power amplifiers, and signal converters. 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.


On the other hand, d882m commercial off-the-shelf (COTS) ICs are the ones, which are already available in the market, often providing flexibility and programmability to support diverse system design needs. These products can be used out-of-the-box, but often needs to be configured for a target application.

Examples of COTS components include field programmable gate arrays (FPGA), microcontrollers/processors, and data converters. The distinction between ASIC and COTS is often subtle, and when a chip manufacturer decides to sell its ASICs into the market, they can become “off-the-shelf” to the original equipment manufacturers (OEMs), who build various computing systems using them.

10.2.4 Board-Level RE

The goal of board-level RE is to identify all components on the board and the connections between them. All of the components used in a design are called the bill of materials (BOM) [1]. The components and parts of a PCB could be any of the following: microprocessors, microcontrollers, decoupling capacitors, differential pairs, DRAMs, NAND flashes, serial EEPROMs, serial NOR flashes, and crystals/oscillators.

There could be silkscreen markings, d882m high-speed serial/parallel ports, program/debug ports, JTAGs, DVIs, HDMIs, SATAs, PCIs, Ethernets, program/debug ports, and display ports [3,48]. To identify the components, test points, and parts of the PCB, silkscreen markings are often used [1]. For example, D101 may be a diode, and Z12 might be a zener diode.

IC identification via chip and die markings. Some electronic components mounted on the PCB can be identified easily through the use of IC markings, but fully custom and semicustom ICs are difficult to identify. Using standard off-the-shelf parts with silkscreen annotations will assist the RE process.

If the ICs d882m have no markings, then the manufacturer’s logo can give an idea of the functionality of the chip. Custom devices, which are developed in-house, are difficult to identify [1], because a custom device could be undocumented, or documentation could be provided only under a nondisclosure agreement.

The first is the prefix, which is the code that is used to identify the manufacturer. It could be a one- to a three-letter code, although a manufacturer might have several prefixes.

The second part d882m is the device code, which is used to identify a specific IC type.

The next part is the suffix, which is used to identify the package type and temperature range. Manufacturers modify their suffixes frequently.

A four-digit code is used for the date, where the first two digits identify the year and the last two identify the number of the week. In addition, manufacturers could cipher the date into a form only known by them.

The marking conventions of a Texas Instruments (TI) chip for the first and second line is shown in Fig. 10.10. The TI chips could have an optional third and fourth line with information related to the trademark and copyright. After identifying the manufacturer and IC markings, the reverse engineer could find the detailed functionality of the chip from the datasheets, which are available on the Internet [50,51].

For an integrated circuit d882m to behave quantum mechanically, the first requirement is very low dissipation. More specifically, all metallic parts need to be made out of a material that has negligible resistance at the qubit operating temperature and at the qubit transition frequency.

The loss d882m of only one energy quantum completely spoils quantum coherence. Low temperature superconductors [2] such as aluminium or niobium are therefore ideal for the task of carrying quantumsignals. For this reason, quantum integrated circuit implementations have been nicknamed “superconducting qubits”1
