Lecture
Differential Amplifier: Small Signal Analysis
Description
This lecture covers the operation and polarization of a bipolar transistor differential amplifier, focusing on small signal analysis, differential gain, common mode gain, and active load configurations. The instructor explains the importance of maintaining symmetry in the amplifier to reject common mode signals and achieve high gain. Topics include differential input and output resistance, equivalent circuits, and half-circuit methods. The lecture also discusses the utilization of active loads to improve amplifier performance and common mode rejection rate.
