/ˈɪntɪˌɡreɪtɪd ˈsɜːrkɪt/

noun … “Miniaturized electronic circuit on a semiconductor chip.”

/ˈrɛktɪfaɪər/

noun … “Circuit that converts alternating current to direct current.”

Rectifier is an electronic circuit or device that converts alternating current (AC) into direct current (DC). Rectification is a fundamental process in power electronics, allowing electrical systems and devices that require steady, one-directional current to operate using AC power sources such as wall outlets or generators. Rectifiers are built primarily using diodes, which enforce one-way current flow.

/ˈdaɪoʊd/

noun … “Semiconductor device that allows current to flow in one direction.”

Diode is a two-terminal electronic component that permits electric current to flow primarily in a single direction while blocking it in the opposite direction. Diodes are fundamental elements in electronic circuits, used for rectification, signal shaping, protection, and voltage regulation. They are built from semiconductor materials, typically silicon, arranged to form a p–n junction.

/ˌkɑːmbɪˈneɪʃənəl ˈsɜːrkɪt/

noun … “Logic circuit with output determined only by current inputs.”

Combinational Circuit is a type of digital logic circuit whose output depends solely on the present values of its inputs, with no reliance on past states or stored memory. Unlike sequential circuits, combinational circuits have no internal state, clock, or feedback loops. They are built entirely from logic gates and implement Boolean expressions directly.

/ˈæmplɪfaɪər/

noun … “Device that increases signal strength.”

Amplifier is an electronic circuit or device that increases the amplitude of a signal, making it stronger in voltage, current, or power without altering the underlying information it carries. Amplifiers are essential in both analog and digital systems, enabling weak signals from sensors, microphones, or antennas to be processed, transmitted, or reproduced effectively.

Key characteristics of Amplifier include:

/ˌsɛmɪkənˈdʌktər/

noun … “Material with controllable electrical conductivity.”

Semiconductor is a material whose electrical conductivity lies between that of a conductor and an insulator. Its conductivity can be modified by adding impurities (doping), applying voltage, or controlling temperature. Semiconductors are the foundation of modern electronics, enabling the creation of transistors, logic gates, diodes, integrated circuits, microprocessors, and memory devices.

/ˈtrænzɪstər/

noun … “Semiconductor device for controlling current.”

Transistor is a semiconductor component used to amplify or switch electronic signals and electrical power. It is the fundamental building block of modern electronic devices, including logic gates, microprocessors, memory, and analog circuits. Transistors control current flow through their terminals—typically called the emitter, base, and collector (for bipolar junction transistors) or source, gate, and drain (for field-effect transistors).

/ˈlɑːdʒɪk ɡeɪts/

noun … “Basic building blocks of digital circuits.”

Logic Gates are fundamental electronic components that perform Boolean operations on one or more binary inputs to produce a single binary output. They form the basis of digital circuits, including processors, memory, and control systems. Logic gates implement basic operations like AND, OR, NOT, XOR, NAND, and NOR, which are combined to create complex computational and control functions.

Key characteristics of Logic Gates include:

/diː-eɪ-siː/

noun … “Converts digital signals to analog signals.”

DAC (Digital-to-Analog Converter) is an electronic component or system that transforms digital data, typically represented as binary numbers, into a continuous analog signal. DACs are crucial in applications where digital information must interface with the physical world, such as audio playback, video display, instrumentation, and control systems.

Key characteristics of DAC include:

/ˈmaɪkroʊkənˌtroʊlər/

noun … “Compact CPU with built-in peripherals.”
