R<sub>a</sub> = resistance in the filter
R<sub>b</sub> = resistance in the filter
(R<sub>a</sub> = R<sub>b</sub>)
C<sub>a</sub> = filter capacitor
C<sub>b</sub> = filter capacitor
(C<sub>a</sub> = C<sub>b</sub>)
R<sub>c</sub> = feedback resistor
R<sub>d</sub> = feedback resistor
Input data: cutoff frequency: 100KHz
Click on "Calculate"
