🔍 Key Concepts

• Emitter-follower (common-collector) configuration basic behavior • Relationship between voltage gain, current gain, and power gain in transistor amplifiers • Typical input and output impedance characteristics of common-emitter, common-base, and emitter-follower stages

💭 Think About

• Think about whether an emitter-follower inverts or nearly copies the input voltage. What does that suggest about its voltage gain compared with 1? • Consider why emitter-followers are often used as buffer stages between a high-impedance source and a low-impedance load. Which parameter (current, voltage, or power gain) makes them useful for this role? • Compare the input impedance of common-base, common-emitter, and emitter-follower configurations. Which one is normally chosen when you want to avoid loading the previous stage?

✅ Before You Answer

• Verify which configuration (common-base, common-emitter, or emitter-follower) typically has the highest input impedance and lowest output impedance. • Check whether the voltage gain of an emitter-follower is significantly greater than 1, approximately 1, or less than 1. • Confirm which configuration is known for providing high current gain while maintaining a voltage gain close to unity.
