Balancing: differential pair
The differential-pair can be considered an anti-series connection of two CS stages. By doing so, its properties can easily be related to those of the CS stage.
Presentation
The presentation “Balancing: differential pair” relates the large-signal and the small-signal static and dynamic transfer, as well as the stationary noise performance of the differential pair to the corresponding properties of the CS stage.
