Detailed Design Procedure

The infinite-gain multiple-feedback circuit for a low-pass network function is shown in Figure 9-3. Use Equation 1 to calculate the voltage transfer function.

Equation 1. GUID-AE656DE4-7E90-4FF3-B8A8-FFC13CD5BFFA-low.gif

This circuit produces a signal inversion. For this circuit, the gain at dc and the low-pass cutoff frequency are calculated using Equation 2.

Software tools are readily available to simplify filter design. The filter design tool is a simple, powerful, and easy-to-use active filter design program. The filter design tool allows the user to create optimized filter designs using a selection of TI operational amplifiers and passive components from TI's vendor partners.
