What we have learnt
- Differential amplifiers are essential for enhancing desired signals while minimizing unwanted noise.
- Understanding common mode and differential signals is crucial for effective circuit design in analog electronics.
- High differential gain and low common mode gain are desirable features in differential amplifiers to achieve optimal performance.
Key Concepts
- -- Differential Signaling
- A method of transmitting signals using two complementary signals to enhance noise immunity.
- -- Common Mode Signal
- The component of the signal that is the same in both inputs to the amplifier and can cause distortion if not properly managed.
- -- Differential Gain
- The amplification applied to the difference between the two input signals, aimed at strengthening the desired signal.
- -- Common Mode Gain
- The amplification of the common mode signal, which ideally should be minimized to prevent distortion.
