What we have learnt
- Multistage amplifiers provide high overall gain by cascading individual amplifier stages.
- The Cascode amplifier configuration improves high-frequency response by mitigating the Miller effect.
- Careful design of coupling and bypass capacitors is crucial for maintaining the bandwidth and performance of amplifiers.
Key Concepts
- -- Multistage Amplifiers
- Amplifiers that consist of multiple stages connected in cascade to achieve a high overall voltage gain.
- -- Cascode Amplifier
- An amplifier configuration combining a Common-Emitter stage with a Common-Base stage to improve high-frequency performance and reduce the Miller effect.
- -- Miller Effect
- A phenomenon where parasitic capacitance in a common-emitter amplifier is amplified, leading to reduced high-frequency response.
- -- RC Coupling
- A method of connecting amplifier stages using resistors and capacitors, allowing AC signals to pass while blocking DC signals.
- -- Voltage Gain
- The ratio of the output voltage to the input voltage in an amplifier, often expressed in decibels (dB).
