Transistor Feedback Circuits Unit 5 – Differential Amplifiers
Exercise 2 – Differential Gain
EXERCISE OBJECTIVE
When you have completed this exercise, you will be able to measure single-ended and
differential gain by using a typical differential amplifier circuit. You will verify your results with
an oscilloscope and a multimeter.
DISCUSSION
- Collector-to-emitter resistor-ratio determines the gain of each half of the differential
amplifier - A = RC/(2 x RE)
