Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a BJT amplifier to achieve a specified voltage gain of 50, given your available resistors and biasing methods.

💡 Hint: Remember to calculate for stability when determining resistor values.

Challenge 2 Hard

Given an experimental setup where the observed lower cutoff frequency is at 900 Hz, calculate the likely input capacitor’s value if the input resistance is known as 10 kΩ.

💡 Hint: Concentrate on re-arranging the formula to isolate the capacitance.
