In a common base amplifier, if R_s is increased to 20K Ohm and R_C is 5K Ohm, analyze the trade-off between gain and bandwidth.
💡 Hint: Reflect on how higher R_s would change our calculated voltage gain.
For an amplifier with a transconductance of 40 mS and output resistance of 10K Ohm, calculate the output voltage if input voltage is 0.1V.
💡 Hint: Analyze the relations among transconductance, resistance, and voltage gain.
