Gain-bandwidth product — The gain bandwidth product (GBW or GB) for an amplifier is the product of the open loop gain (constant for a given amplifier) and its 3 dB bandwidth. Relevance to design This quantity is commonly specified for operational amplifiers, and allows… … Wikipedia
Bandwidth (signal processing) — Bandwidth is the difference between the upper and lower cutoff frequencies of, for example, a filter, a communication channel, or a signal spectrum, and is typically measured in hertz. In case of a baseband channel or signal, the bandwidth is… … Wikipedia
Gain compression — in an electronic amplifier circuit is a reduction in differential or slope gain caused by nonlinearity of the transfer function of the amplifying device. This nonlinearity may be caused by heat due to power dissipation, or by overdriving the… … Wikipedia
Bandwidth — Bande passante Pour les articles homonymes, voir bande. La bande passante (angl. bandwidth) est un intervalle de fréquences pour lesquelles la réponse d un appareil est supérieure à un minimum. Elle est généralement confondue avec la largeur de… … Wikipédia en Français
Bandwidth — Dieser Artikel erläutert die Bandbreite als technischen Begriff; für ein gleichnamiges Wechselkurssystem siehe Wechselkursbandbreite. Für die Bandbreite als Begriff in der Numerischen Mathematik siehe Bandmatrix. Bandbreite B bezeichnet die… … Deutsch Wikipedia
Coding gain — In coding theory and related engineering problems, coding gain is the measure in the difference between the signal to noise ratio (SNR) levels between the uncoded system and coded system required to reach the same bit error rate (BER) levels when … Wikipedia
Process gain — In a spread spectrum system, the process gain (or processing gain ) is the ratio of the spread (or RF) bandwidth to the unspread (or baseband) bandwidth. It is usually expressed in decibels (dB).For example, if a 1 kHz signal is spread to 100 kHz … Wikipedia
Open-loop gain — The open loop gain of an operational amplifier is the gain obtained when no feedback is used in the circuit. Open loop gain is usually exceedingly high; in fact, an ideal operational amplifier has infinite open loop gain. Typically an op amp may… … 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
Modelocking — Mode locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10 12s) or femtoseconds (10 15s).The basis of the technique is to induce a fixed phase… … Wikipedia
Fully differential amplifier — A fully differential amplifier, usually referred to as an FDA for brevity, is a DC coupled high gain electronic voltage amplifier with differential inputs and differential outputs. In its ordinary usage, the output of the FDA is controlled by two … Wikipedia
