An analog circuit (or analogue circuit) is an electric circuit that operates on analog signals. ...more on Wikipedia about "Analog circuit"

An analog multiplier is a device which takes two analog signals and produces an output which is their product. In many (if not most) applications they are used in what most non mathematicians would consider to be a divider, that is they multiply by a fraction in order to obtain a division. Of course it is also possible to use such circuits to implement related functions such as squares (apply signal to both inputs), and square roots. ...more on Wikipedia about "Analog multiplier"

Two electric circuits are said to be equivalent with respect to a pair of terminals if the voltages across the terminals and currents through the terminals ...more on Wikipedia about "Analysis of resistive circuits"

Automatic Frequency Control (AFC) is a method (or device) to automatically maintain a tuning of electromagnetic radiation (radio or microwave) signal to desired frequency. ...more on Wikipedia about "Automatic frequency control"

Automatic gain control (AGC) is an electronic system found in many types of devices. Its purpose is to control the gain of a system in order to maintain some measure of performance over a changing range of real world conditions. ...more on Wikipedia about "Automatic gain control"

A balance detector consists of several photo-detectors which can eliminate unwanted noise output. ...more on Wikipedia about "Balance detector"

In a hybrid set, hybrid coil, or resistance hybrid, balancing network is a circuit used to match, i.e., to balance, the impedance of a uniform transmission line, i.e., twisted metallic pair, over a selected range of frequencies. A balancing network is required to ensure isolation between the two ports of the four-wire side of the hybrid. ...more on Wikipedia about "Balancing network"

A bandgap voltage reference is a voltage reference circuit widely used in integrated circuits, usually with an output voltage around 1.25 V, close to the theoretical bandgap of silicon at 0 K. ...more on Wikipedia about "Bandgap voltage reference"

A boost converter (step-up converter) is a power converter with an output dc voltage greater than its input dc voltage. It is a class of switching-mode power supply (SMPS) containing at least two semiconductor switches and at least one energy storage element. Filters made of inductor and capacitor combinations are often added to a converter’s output to improve performance. ...more on Wikipedia about "Boost converter"

Brokaw bandgap reference is a voltage reference circuit widely used in integrated circuits, with an output voltage around 1.25 V with only little temperature dependence. This particular circuit is one type of a bandgap voltage reference, named after the author of its first publication. ...more on Wikipedia about "Brokaw bandgap reference"

The buck-boost converter is a type of DC-DC converter that has an output voltage magnitude that is either greater than or less than the input voltage magnitude. It is a switch mode power supply with a similar circuit topology to the boost converter and the buck converter. The output voltage is adjustable based on the duty cycle of the switching transistor. One drawback of this converter is that the switch does not have a terminal at ground; this complicates the driving circuitry. Also, the polarity of the output voltage is opposite the input voltage. ...more on Wikipedia about "Buck-boost converter"

The capacitor-input filter is a type of filter circuit. Filter circuits are used to remove the AC component from the rectified output and allows only the DC component to reach the load. ...more on Wikipedia about "Capacitor-input filter"

A chopper circuit is used to refer to numerous types of electronic switching devices and circuits. The term has become somewhat ill-defined, and as a result is much less used nowadays than it was perhaps 30 or more years ago. ...more on Wikipedia about "Chopper (electronics)" www.shortopedia.com never sleeps.

Chua's circuit is a simple electronic circuit that exhibits classic chaos theory behavior. First introduced in 1983 by Leon O. Chua, its ease of construction has made it an ubiquitous real-world example of a chaotic system, leading some to declare it 'a paradigm for chaos'. ...more on Wikipedia about "Chua's circuit"

In electronics, a comparator is a device which compares two voltages or currents, and switches its output to indicate which is larger. More generally, the term is also used to refer to a device that compares two items of data. ...more on Wikipedia about "Comparator"

A current mirror is a circuit designed to copy a current flowing through one active device by controlling the current in another active device of a circuit, keeping the output current constant regardless of loading. The current being 'copied' can be, and sometimes is, a varying signal current. ...more on Wikipedia about "Current mirror"

A current source is an electrical or electronic device that delivers or absorbs electric current. Current sources can be theoretical or practical. ...more on Wikipedia about "Current source"

A cycloconverter or a cycloinverter converts an AC waveform, such as the mains supply, to another AC waveform of a lower frequency. They are most commonly used in three phase applications — while single phase cycloconverters are possible, they are so impractical that they are never used in real systems. The amplitude and the frequency of input voltage to a cycloconverter tend to be fixed values, whereas both the amplitude and the frequency of output voltage of a cycloconverter tend to be variable. A circuit that converts an AC voltage to another AC voltage at the same frequency is known as an AC/AC chopper. ...more on Wikipedia about "Cycloconverter"

Electronic filters are electronic circuits which perform signal processing functions. Electronic filters can be: ...more on Wikipedia about "Electronic filter"

An electronic mixer is a device for mixing two or more electronic signals. There are two basic types of mixer. Additive mixers add two signals together, and are used for such applications as audio mixing. Multiplying mixers multiply the signals together, and produce an output containing both original signals, and new signals that have the sum and difference of the frequency of the original signals. ...more on Wikipedia about "Electronic mixer"

The gyrator is an electric circuit which inverts an impedance. In other words, it can make a capacitive circuit behave inductively, a bandpass filter behave like a band-stop filter, and so on. The concept was invented around 1948 by B.D.H. Tellegen of Philips Research Laboratories, Eindhoven ("The gyrator, a new electric network element", Philips Res. Rep. 3 (1948) pgs 81-101). It is primarily used in active filter design. ...more on Wikipedia about "Gyrator"

An H-bridge is an electronic circuit which enables DC electric motors to be run forwards or backwards. These circuits are often used in robotics. H-bridges are available as integrated circuits, or can be built from separate components. ...more on Wikipedia about "H-bridge"

In electronics, especially audio and sound recording, an impedance bridging or voltage bridging connection is one which maximizes voltage transfer to the load. The other typical configuration is an impedance matching connection, which maximizes power delivered to the load. ...more on Wikipedia about "Impedance bridging"

Kirchhoff's circuit laws are a pair of laws that deal with the conservation of charge and energy in electrical circuits, and were first described in 1845 by Gustav Kirchhoff. Widely used in electrical engineering, they are also called Kirchhoff's rules or simply Kirchhoff's laws (see also Kirchhoff's laws for other meanings of that term). ...more on Wikipedia about "Kirchhoff's circuit laws"
