The chapter delves into the analysis and numerical examples of differential amplifiers, emphasizing the importance of DC voltage and common mode voltage for effective operation. Key concepts include differential and common mode gain along with an exploration of signal distortion in relation to the operating points of transistors. The chapter concludes by discussing the impact of input common mode voltage on amplifier performance.
The suitable range of common mode voltage is critical for the proper functioning of a differential amplifier.
Both differential and common mode gain significantly influence the overall performance and signal integrity of amplifiers.
Operating points must be carefully selected to prevent distortion and ensure optimal signal swing in amplifiers.
An amplifier that amplifies the difference between two input voltages and rejects any voltages that are common to both inputs.
The average voltage present at both inputs of a differential amplifier, which can affect the performance of the amplifier.
A parameter that quantifies the performance of transistors; it measures how effectively an input voltage can change the output current.
The DC biasing point of a transistor in an amplifier circuit, chosen to ensure linear operation within the maximum signal swing limits.
