I would like to know how to design an amplifier similar to the attached circuit with set -3db points, the lower on the order of 10Hz, and the higher on the order of 10kHz.(adsbygoogle = window.adsbygoogle || []).push({});

I have designed amplifiers to work with a set gain, but have not dealt with frequency response before.

I designed an amp on PSPICE with a theoretical gain of over 200, but when I tacked on a low-pass filter, the output pretty much went to 0.

Therefore, how would you go about designing for gain in addition to -3db points?
