PRODUCTION DATA
The infinite-gain multiple-feedback circuit for a low-pass network function is shown in. Use Equation 2 to calculate the voltage transfer function.
This circuit produces a signal inversion. For this circuit, the gain at DC and the low-pass cutoff frequency are calculated by Equation 3:
Software tools are readily available to simplify filter design. The WEBENCH® Filter Designer is a simple, powerful, and easy-to-use active filter design program. The WEBENCH® Filter Designer lets you create optimized filter designs using a selection of TI operational amplifiers and passive components from TI's vendor partners.
Available as a web based tool from the WEBENCH Design Center, the WEBENCH Filter Designer allows you to design, optimize, and simulate complete, multistage, active-filter solutions within minutes.
