So I need to design a multistage amp using bjt's (npn and/or pnp). I need a midband gain of 200, F_low of 100 Hz, and F_high of 22 kHz. I have tried some CE-CE and cascade configurations, and I've been getting close to the right gain, but my bandwidth is way too large (1-10MHz). I've been searching for ways to narrow the bandwidth but I can only find ways to make it wider.
Anyway, what I'm trying to ask is does anybody know a configuration of bjt amps that could get me a narrow bandwidth?
