LMF120 Mask-Programmable Switched-Capacitor Active Filter System

The LMF120 is a mask-programmable switched-capacitor filter capable of realizing virtually any filter response up to twelve poles using six independent biquad blocks. It is customized to meet specific application requirements through the use of automated design techniques. Circuit realization occurs.

LMF120 Features

* Mask-programmable for virtually any filter response

* All filter types (low-pass, high-pass, bandpass, notch, all-pass)

* All filter approximations (Butterworth, Chebyshev, Ellip- tic, Bessel, etc.)

* Up to 12 poles and right-half-plane zeros in one 16-pin package
