Dear members,
I have a problem designing a non inverting single supply band pass filter, with the use of an LM358. I have worked the calculations for the gain and they seem to be right, Then I worked out the calculations from my school book as attached in one of the attachments and simulated on proteus something like in the below attachment, I can't seem to see what is going wrong with my simulation, since I need an bandpass filter for a 150mV ac signal to be amplified, letting frequencies between 200Hz20kHz to pass. The outputs can't seem to be what I need as I need around 25.66dB in gain. Any help would be greatly appreciated as I can't seem to find a way out, Thanks in advance.
Regards
Fiat Uno
