1. Gain The gain of an amplifier relates to how much it can boost the amplitude of a signal. This parameter is frequently expressed in decibels (dB). Gain is defined as the output amplitude divided by the input amplitude into mathematical terms. 2. Output dynamic range The range between th...
Solid-state refers electronic components, devices and systems based entirely on semiconductor materials. What is a semiconductor optical amplifier? A semiconductor optical amplifier (SOA) is an element found in semiconductors thatamplifieslight. Users can find SOAs in optical transceiver modules used to ...
This type of amplifier is very useful electronic circuitry that can provide good gain boosting services and output characteristics, but there is a possibility that it could increase the voltage level too much. This can induce a lot of noise and distortion into the signal, resulting in serious da...

The Crest Audio CD3000 is a Class-D amplifier capable of delivering 1500 watts per channel into a 2Ohm load. Amazingly for such a brute, the CD3000 only takes up 2U of rack space, and weighs a mere (for a power amp) 21kg.Here's a good question: just why are power amplifiers so...
Class A amplifier has a conduction angle of 360 degrees. These amplifiers offer high linearity and gain but at the cost of efficiency. The efficiency of a Class A amplifier is typically limited to 15~30%. The amplifier circuit often has an input stage that pre-amplifies the weak signal from...
