I am designing a basic 100kHz active bandpass filter using opamps (LF353). I am only interested in receiving the 100kHz frequency (might drift a few kHz) from my input signal. I have used a basic Fliege bandpass filter, because it has low component count, simple, uses only 2 opamps and has adjustable frequency and Q control.
V(in) = 2v(p-p) sine wave 100kHz (for testing)
f1 = 90kHz
f2 = 110kHz
Any suggestions for improvement or new designs?
I have no restrictions except that I would like to use no more than 2 opamps, preferably LF353.
This is my design:
