Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I am new to this website. I am having troubles in designing a common source amplifier with a voltage gain, Av=26 dB (no bypass capacitor) and a gain of 40 DB (with a bypass capacitor) and a frequency of 100-1000HZ. Can anyone please guide me to calculate the value of the bypass capacitor? I searched everywhere for the methods of finding the capacitors values but still in vain.

thank you very much for all your help.

thanks,

peace
