## Technical glossary 

Analog  A type of signal in an electronic circuit that takes on a continuous range of values rather than only a few discrete values. 

ASIC  An Application Specific Integrated Circuit is an integrated chip, custom-designed for a specific application. 

ASSP  An Application Specific Standard Product is a semiconductor device integrated circuit (IC) dedicated to a specific application and sold to more than one user. 

Audio CODEC  The interface between analog signals (such as the human voice) and the digital data processing inside a mobile phone, determining voice quality. 

BCD process platform  The incorporation of analog components (Bipolar), digital components (CMOS) and high-voltage transistors (DMOS) on the same die to reduce the number of components required in the bill of materials, minimise board space, costs and the parasitic losses in comparison to a non-integrated solution. 

Buck converter  A DC-to-DC buck converter accepts a direct current input voltage and produces a direct current output voltage to a plurality of channels. 

CAD  Computer Aided Design usually refers to a software tool used for designing electronics hardware or software systems. 

CDMA  Code Division Multiple Access is an alternative to GSM technology for mobile wireless networks. 

Chips  Electronic integrated circuits. 

CMOS  Complementary Metal Oxide Semiconductor: the most popular class of semiconductor manufacturing technology. 

Digital  A type of signal used to transmit information that has only discrete levels of some parameter (usually voltage). 

Fabless  A company that designs and delivers semiconductors by outsourcing the fabrication (manufacturing) process. 

FET  A Field Effect Transistor uses an electric field to control the shape and hence the conductivity of a channel of one type of charge carrier in a semiconductor material. 

Foundry  A manufacturing plant where silicon wafers are produced. 

Hi-Fi  High-Fidelity is the reproduction of sound with little or no distortion. 

IC  Integrated Circuit: an electronic device with numerous components on a single chip. 

Imaging  The capture and processing of images via an image sensor for use by an electronic device to send to a display for viewing by a user. 

Liquid Crystal Display (LCD) A display technology found in many portable electronics products, including personal organisers, cellular handsets and notebook computers. 

LDO  Low dropout voltage regulators are used in battery operated systems, where the output voltage is typically lower than the input voltage. 

LED  A Light Emitting Diode is a semiconductor device that emits light when charged with electricity, often used for LCD display backlights. 

Mixed signal  A combination of analog and digital signals being generated, controlled or modified on the same chip. 

OEM  An Original Equipment Manufacturer that builds products or components that are used in products sold by another company. 

Power Management  The management of the power requirements of various subsystems, important in handheld and portable electronics equipment. 

PMIC  Power Management IC. 

Semiconductor  A base material halfway between a conductor and an insulator, which can be physically altered by mixing in certain atoms. Semiconductors form the basis for present-day electronics. 

Silicon  A semi-metallic element used to create a wafer – and the most common semiconductor material – in about 95% of all manufactured chips. 

Smartphone  A mobile phone offering advanced capabilities, often with pc-like functionality (PC-mobile handset convergence). A smartphone runs complete operating system software providing a standardised interface and platform for application developers. 

Smart Mirror™  A technology patented by Dialog Semiconductor which simplifies circuit design and provides very low current consumption in Power Management circuits. 

SmartPulse™  A wireless sensor network connectivity solution based on the DECT ULE (Ultra Low Energy) standard for home automation applications. 

SmartXtend™  A technology patented by Dialog Semiconductor that extends the life and reduces power consumption of high-resolution, passive matrix OLED displays. 

Subcontractor  A business that signs a contract to perform part or all of the obligations of another’s contract. 

Tablet PC  A tablet PC refers to a slate- or tablet-shaped mobile computer device, equipped with a touchscreen or stylus. 

TAM  Total addressable market, TAM measures the potential market for your product – and your product only – assuming you could reach 100% of your customers. 

Ultrabook™  A higher-end, compact sub-notebook that is designed to be compact, thin and light without compromising performance and battery life. Ultrabooks™ typically feature low power processors and solid-state drives. 

USB  Universal Serial Bus: a universal interface standard to connect different electronics devices. 

Wafer  A slice of silicon from a 4, 5, 6 or 8 inch diameter silicon bar and used as the foundation on which to build semiconductor products.
