82Darlington transistor — Circuit diagram of a Darlington pair using NPN transistors In electronics, the Darlington transistor (often called a Darlington pair) is a compound structure consisting of two bipolar transistors (either integrated or separated devices) connected …
83Transformer types — Circuit symbols Transformer with two windings and iron core. Step down or step up transformer. The symbol shows which winding has more turns, but not usually the …
84Electronic amplifier — A practical amplifier circuit An electronic amplifier is a device for increasing the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In… …
85Tube sound — (or valve sound) is the characteristic sound associated with a vacuum tube based audio amplifiers. Some audiophiles prefer the sound that is produced by the distortion characteristics of tube based amplifiers. The audible significance of tube… …
86Current source — Figure 1: An ideal current source, I, driving a resistor, R, and creating a voltage V A current source is an electrical or electronic device that delivers or absorbs electric current. A current source is the dual of a voltage source. The term… …
87Bipolar transistor biasing — Bipolar transistor amplifiers must be properly biased to operate correctly. In circuits made with individual devices (discrete circuits), biasing networks consisting of resistors are commonly employed. Much more elaborate biasing arrangements are …
88Miller theorem — refers to the process of creating equivalent circuits. It asserts that a floating impedance element supplied by two voltage sources connected in series may be split into two grounded elements with corresponding impedances. There is also a dual… …
89Operational amplifier applications — This article illustrates some typical applications of operational amplifiers. A simplified schematic notation is used, and the reader is reminded that many details such as device selection and power supply connections are not shown. Contents 1… …
90electronics — /i lek tron iks, ee lek /, n. (used with a sing. v.) the science dealing with the development and application of devices and systems involving the flow of electrons in a vacuum, in gaseous media, and in semiconductors. [1905 10; see ELECTRONIC,… …
