7.2.2 Detailed Design Procedure

The infinite-gain multiple-feedback circuit for a low-pass network function is shown in Figure 7-7. Use Equation 1 to calculate the voltage transfer function.

Equation 1. OPA627 OPA637

This circuit produces a signal inversion. For this circuit the gain at DC and the low pass cutoff frequency can be calculated using Equation 2.

Equation 2. OPA627 OPA637

Software tools are readily available to simplify filter design. Available as a web-based tool from the Design tools and simulation web page, the Analog Filter Designer allows the user to design, optimize, and simulate complete multistage active filter solutions within minutes.
