100kHz, 6th Order Pseudo-Butterworth
Frequency Response
TEXTBOOK BUTTERWORTH
PSEUDO-BUTTERWORTH
fO1 = 100kHz
Q1 = 1.9319
fO1 = 100kHz Q1 = 1.9319
fO2 = 100kHz
Q2 = 0.7071
fO2 = 100kHz Q2 = 0.7358
fO3 = 100kHz
Q3 = 0.5176
fO3 = 100kHz Real Poles
fO4 = 100kHz Real Poles
The complex, 2nd order section of the textbook design
with the lowest Q is replaced with two real first order poles.
The Q of another section is slightly altered such that the
final filter’s response is indistinguisable from a textbook
Butterworth response.
The fO and Q values listed above can be entered in
FilterCAD’s Enhanced Design window as a custom re-
sponse filter. After entering the coefficients, FilterCAD will
produce a schematic of the circuit. The procedure is as
follows:
1. After starting FilterCAD, select the Enhanced Design
window.
2. Select the Custom Response and set the custom FC to
1Hz.
3. In the Coefficients table, go to the Type column and click
on the types listed and set the column with two LP types
and two LP1 types. This sets up a template of a 6th order
filter with two 2nd order lowpass sections and two 1st
order lowpass sections.
4. Enter the fO and Q coefficients as listed above. For a
Butterworth filter, use the same coefficients as the
example circuit above except set all of the fO to 1Hz.
5. Set the custom FC to the desired cutoff frequency. This
will automatically multiply all of the fO coefficients. You
have now finished the design of the filter and you can
click on the frequency response or step response
buttons to verify the filter’s response.
6. Click on the Implement button to go on to the filter
implementation stage.
7. In the Enhanced Implement window, click on the Active
RC button to choose the LTC1563-2 part. You are now
done with the filter’s implementation. Click on the
schematic button to view the resulting circuit.
