Multi-transistor amplifiers consist of combined configurations for improved overall performance.
Output impedance can be decreased or input impedance increased by cascading different amplifier stages.
Different amplifier configurations have their strengths in either voltage or current amplification, often requiring integration with other stages.
Common Emitter Amplifier (CE)
A configuration known for its high voltage gain, potentially suitable for voltage mode amplification, but may require buffering for optimal performance.
Common Collector Amplifier (CC)
A configuration with low voltage gain but high input impedance that can act as a voltage buffer.
Common Base Amplifier (CB)
A configuration characterized by low input impedance and suitability for current mode amplification but limited voltage gain.
Cascaded Configuration
The arrangement of multiple amplifiers in sequence to achieve desired impedance characteristics and improved performance.
