8.2.2 Detailed Design Procedure

The infinite-gain multiple-feedback circuit for a low-pass network function is shown in GUID-2B698E47-5F6C-4E06-ADF1-E1035369277E.html#SBOS40655. Use #SBOS3778114 to calculate the voltage transfer function.

Equation 1. GUID-1E140805-5FA5-4329-A030-A252744EB0F0-low.gif

This circuit produces a signal inversion. For this circuit, the gain at dc and the low-pass cutoff frequency are calculated by #SBOS3772832:
