Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a self-biased Common Emitter Amplifier with a target gain of 100. Specify component values for the circuit.

💡 Hint: Use the gain formula and remember the roles of resistors.

Challenge 2 Hard

Evaluate how a change in β from 100 to 50 affects the performance of a fixed bias vs. a self-bias amplifier with the same supplied voltage.

💡 Hint: Focus on how each bias configuration responds to changes in β.
