Uses one section of OP-11FY quad opamp or equivalent in circuit having Q of 4.7 and providing closed-loop gain of 200 or 46 dB. Opamp selected should have open-loop gain of 5 to 10 times required gain at resonance. Adiust resistor values to tune centerfrequency.-D. Van Dalsen, Need an Active Filter?
