Challenge Problems
Push your limits with challenges.
Question 1
You are tasked with designing a common emitter amplifier with a specific voltage gain of 50. If the transconductance g_m is 5 mS, calculate the required values for R_C and R_E assuming a specific configuration.
💡 Hint: First isolate R_C or R_E and consider realistic resistor values.
Question 2
Explain how to mitigate input signal loss while keeping the emitter resistor in a circuit and provide a design example using bypass capacitors.
💡 Hint: Refer to the RC time constant and how it affects frequency response.
