What we have learnt
- Differential amplifiers play a crucial role in signal processing by amplifying the difference between two signals while rejecting common noise.
- The key parameters for differential amplifiers include differential mode gain, common mode gain, and their implications on circuit performance.
- Transistor implementations, such as BJT and MOSFET, determine the overall function and efficiency of differential amplifiers in practical applications.
Key Concepts
-
Term: Differential Mode Gain
Definition: The gain of a differential amplifier when it amplifies the difference between its two input signals.
-
Term: Common Mode Gain
Definition: The gain of a differential amplifier for signals that are common to both inputs.
-
Term: Transistor Realization
Definition: Refers to the implementation of differential amplifiers using different types of transistors (BJT or MOSFET) and their configurations to achieve desired performance.
