stage coupling
1Direct coupling — In electronics, direct coupling (also called direct wired contact and conductive charging) is a way of interconnecting two circuits such that, in addition to transferring the AC signal (or information), the first stage also provides DC bias to… …
2Capacitive coupling — In electronics, capacitive coupling is the transfer of energy within an electrical network by means of the capacitance between circuit nodes. This coupling can have an intentional or accidental effect. Capacitive coupling is typically achieved by …
3Oxidative coupling of methane — The oxidative coupling of methane (OCM) is a type of chemical reaction discovered in the 1980s for the direct conversion of natural gas, primarily consisting of methane, into value added chemicals. Direct conversion of methane into other useful… …
4Box coupling — Box Box, n.; pl. {Boxes} [As. box a small case or vessel with a cover; akin to OHG. buhsa box, G. b[ u]chse; fr. L. buxus boxwood, anything made of boxwood. See {Pyx}, and cf. {Box} a tree, {Bushel}.] 1. A receptacle or case of any firm material… …
5Output transformerless — (OTL) is a term which describes a subset of vacuum tube audio power amplifier topologies, all of which omit an output transformer for the purpose of greater linearity and fidelity. Conventional vacuum tube amplifier designs rely upon an output… …
6Output TransformerLess — (audio amplifier) = In the larger scope of vacuum tube audio amplifiers Output TransformerLess (OTL) describes a specific subset of audio power amplifier topologies, all of which have a single common attribute: unlike conventional vacuum tube… …
7Parasitic oscillation — is an undesirable oscillation caused by feedback. The problem occurs notably in RF [1], audio, and other electronic amplifiers[2] as well as in digital signal processing.[3] It is one of the fundamental issues addressed by control theory.[4] …
8Multistage amplifiers — The performance obtainable from a single stage amplifier is often insufficient for many applications, hence several stages may be combined forming a multistage amplifier. These stages are connected in cascade, i.e. output of the first stage is… …
9Electronic 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… …
