A common source amplifier offers high voltage gain, making it ideal for amplifying weak signals. It provides good input impedance and low output impedance, which enhances its compatibility with various circuits. Additionally, this configuration allows for easy phase inversion, which can be beneficial in certain applications. Overall, its simplicity and effectiveness make it a popular choice in analog electronics.
The output impedance of a common source amplifier circuit is typically high. This is because the common source amplifier uses a resistor to provide biasing, which results in a high output impedance. However, this can be mitigated by using a current source instead of a resistor for biasing.
the same amount as the drain
Yes, the common source amplifier is out of phase. It inverts the input signal, meaning that when the input voltage increases, the output voltage decreases, and vice versa. This phase shift is a characteristic feature of common source configurations in field-effect transistors (FETs) and bipolar junction transistors (BJTs).
The common mode rejection ratio of an ideal amplifier is infinity.

advantage of inverting amplifier
it is mainly used for increasing the gain of the circuit

current amplifier
a differential amplifier helps to increase the CMRR which in turn helps avoid unwanted signals that couple into the input to get propagated. IT also helps to increase the signal to noise ratio. furthermore it provides larger output voltage swings.
