Challenge Problems
Push your limits with advanced challenges
A BJT has a collector current of 10 mA, and its diffusion capacitance is measured at 20 pF. If the current varies, calculate the new diffusion capacitance if it increases to 20 mA.
💡 Hint: Use the relationship between collector current and diffusion capacitance.
In a high-frequency application, how would you optimize the design to minimize the impact of collector-base junction capacitance on amplifier gain?
💡 Hint: Consider how changes in amplifier gain or configuration can mitigate these effects.
