SUMMARY

The discussion focuses on designing a two-stage amplifier using common collector and common emitter configurations. The user reports achieving a gain of only 1 despite biasing for midpoint operation. The circuit includes a load resistor R2 and a parallel resistor R14 of 8 ohms, which affects the overall gain. Without R14, the expected gain should be approximately 4, calculated as 800 ohms divided by 200 ohms.

PREREQUISITES
  • Understanding of common collector and common emitter amplifier configurations
  • Knowledge of biasing techniques for midpoint operation
  • Familiarity with gain calculations in amplifier circuits
  • Basic circuit analysis skills, including parallel resistor combinations
NEXT STEPS
  • Research common collector amplifier design and its applications
  • Learn about biasing methods for transistor amplifiers
  • Study gain calculation techniques for multi-stage amplifiers
  • Explore the effects of load resistors on amplifier performance
USEFUL FOR

Electronics engineers, hobbyists designing audio amplifiers, and students studying amplifier circuit design.

Hi, I am trying to build an amplifier with 2 stages, common collector and common emitter. I biased for midpoint operation in them but i have a gain of only 1, don't know where I am going wrong.

Thats the circuit, any help is greatly appreciated

R14 is only 8 ohms and this is in parallel with the load resistor R2.

Without it, the gain should be a bit less than 4. ie 800 / 200
