Description

This lecture explains how differential amplifiers can suppress common mode noise when the circuit is symmetric, but in reality, imperfections like finite current source impedance can lead to common mode signal appearing at the output. The impact of these imperfections on the circuit's performance is discussed through an example, highlighting the importance of common mode rejection ratio.
