What is the common source amplifier?

In electronics, a common-source amplifier isOne of the three basic single stage field-effect transistor (FET), amplifier topologies. These are typically used as voltage or transconductance amplifiers. The easiest way to determine if a transistor is a FET. is common source, commonDrain, or commonGate isTo see where theSignal enters and then leaves.

Does a commonNegative feedback on collector amplifier

Negative, or degenerative feedback has theAn amplifier circuit’s stability is improved by having less output variation for a given input signal. Common-collector amplifiers are prone to negative feedback. thePlacement theLoad resistor between emitter & ground

What is common sourceWhy amplifier? isSo-called?

When theInput signal isApply at theGate terminal sourceterminal, then the output voltage isAmplified and gained across the resistor at theLoad in theDrain terminal. This isSo called a common source amplifier. Here sourceActs as a commonTerminal between theInput and output
