Challenge Problems
Push your limits with challenges.
Question 1
If you are designing a CE amplifier with an active load and need a collector current of 5mA with a supply voltage of 15V. Calculate the required Beta if R_B is 1.5MΩ.
💡 Hint: Consider knowing V_BE(on) for your transistors.
Question 2
Given two BJTs in an active load configuration, if their Beta values are 150 and 300 respectively, how would you bias them to achieve equal collector currents of 10mA?
💡 Hint: Use the principle of ensuring collector currents are equivalent while adjusting base widths.
