Microchip FilterLab® is an innovative online tool that simplifies the design of active filters, which consist of resistors, capacitors, and op amps. It generates the frequency response of the circuit as well as the SPICE model of the designed filter. It is available at no cost on Microchip's FilterLab website. Figure 1 illustrates some of the tool's inputs and outputs.
