  • Guitar amplifier — Mesa Boogie Mark IV, a guitar combo amplifier A guitar amplifier (or guitar amp) is an electronic amplifier designed to make the signal of an electric or acoustic guitar louder so that it will produce sound through a loudspeaker. Most guitar… …   Wikipedia

  • Logarithmic video amplifier — A logarithmic video amplifier or LVA is typically part of radar and electronic countermeasures microwave systems and sonar navigation systems, used to convert a very large dynamic range input power to an output voltage that increases… …   Wikipedia

  • Negative feedback amplifier — Figure 1: Ideal negative feedback model A negative feedback amplifier (or more commonly simply a feedback amplifier) is an amplifier which combines a fraction of the output with the input so that a negative feedback opposes the original signal.… …   Wikipedia

  • Optical amplifier — An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from… …   Wikipedia

  • Operational amplifier — A Signetics μa741 operational amplifier, one of the most successful op amps. An operational amplifier ( op amp ) is a DC coupled high gain electronic voltage amplifier with a differential input and, usually, a single ended output.[1] An op amp… …   Wikipedia

  • Current-feedback operational amplifier — Representative schematic of a current feedback op amp or amplifier. The current feedback operational amplifier otherwise known as CfoA or CfA is a type of electronic amplifier whose inverting input is sensitive to current, rather than to voltage… …   Wikipedia

  • Electronic 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… …   Wikipedia

  • Valve audio amplifier - technical — Circuitry and performance Characteristics of valves Valves are very high input impedance (near infinite in most circuits) and high output impedance devices. They are also high voltage / low current devices.While valves themselves are described… …   Wikipedia

  • Linear amplifier — A linear amplifier is an electronic circuit whose output is proportional to its input, but capable of delivering more power into a load. The term usually refers to a type of radio frequency (RF) power amplifier, some of which have output power… …   Wikipedia

  • Distributed amplifier — Distributed amplifiers are circuit designs that incorporate transmission line theory into traditional amplifier design to obtain a larger gain bandwidth product than is realizable by conventional circuits. N stage traveling wave amplifier …   Wikipedia

  • Optical parametric amplifier — An optical parametric amplifier, abbreviated OPA, is a laser light source that emits light of variable wavelengths by an optical parametric amplification process. Contents 1 Optical parametric generation (OPG) 2 Optical parametric amplification… …   Wikipedia
