Question 1
Design a CE amplifier with R_E = 200Ξ© providing a gain of at least 50. Considering R_C needs to be much higher than R_E, suggest values while maintaining stability.
π‘ Hint: Remember that increasing R_C directly boosts gain while ensuring R_E supports stability against variations.
Question 2
Analyze how introducing a capacitor across R_E would change the amplifier's input and output characteristics.
π‘ Hint: Consider the frequency-dependent behavior of capacitors in AC circuits.
