2nd Order Low-Q Active Filter Design
This tool calculated the required resistor and capacitor values for a second order low-Q active filter. The routine assumes the input signal swing will be differential peak swing of 80%*VDD. Given the SNR, and the swing the resistor and capacitors can be sized. The filter has all real poles and thus the Q is limited to 0.5. Single Pole Active Filter Design
This tool calculated the required resistor and capacitor values for a single pole active filter. The routine assumes the input signal swing will be differential peak swing of 80%*VDD. Given the SNR, and the swing the resistor and capacitors can be sized.
