Simple Single Pole Active Filter Circuit

This circuit is a design circuit for 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. This is a simple form circuit.

This is the figure of the circuit;
