This is an audio compressor/AGC (automatic gain control) with an astonishing 75db input voltage range. A P-Channel JFET is used as a variable resistance element that is applied as a variable ...

AGC (automatic gain control) amplifiers are frequently used devices. Their gain is a function of the level of their input signal. The main function of AGC amplifiers is compression of a signal, but ...

Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...

International Solid-State Circuits Conference in San Francisco always seems to make space for audio amplifier developments, and this year is no exception, with some extraordinary distortion and noise ...

1. Is Amplifier Weight an Indicator of Robust Amplifier Design? You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before you can generalize about weight ...
