I am trying to understand an answer a question from a recent lab examining BJT amplifiers, specifically a question about commonbase amplifiers.
Question:
What is the effect of not bypassing the base resistors R1 and R2 in the schematic of the common base amplifier schematic attached?
I can see that given a periodic input (sinusoidal in our case), an increase in frequency will slowly begin to bypass the resistors R1, and R2. If the Capacitor C1 were not connected to ground, the base current would be lower and the gain would be smaller. Is this correct? I am having trouble understanding exactly what is supposed to happen.
Thanks.
