Transistor Feedback Circuits Unit 4 – Multistage Amplifier Feedback
Exercise 1 – Shunt-Series Current Gain
EXERCISE OBJECTIVE
When you have completed this exercise, you will be able to calculate and measure shunt-series
current gain by using a typical shunt-series multistage amplifier circuit. You will verify your
results with an oscilloscope.
DISCUSSION
- Known as a current amplifier, current gain (Ai) equals the shunt resistance (Rsh) divided by
the series resistance (Ref).
