  Take the Mystery Out of the Switched Capacitor Filter &mdash AN40
  PDF, 3.0 Mb, Archivo publicado: marzo 1, 1990
  This note presents guidelines for circuits utilizing LTC's switched capacitor filters. The discussion focuses on how to optimize filter performance by optimizing the printed wiring board, the power supply, and the output buffering of the filter. Many additional topics are discussed such as how to select the proper filter response for the application and how to characterize a filter's THD for DSP applications.

  Application Note 40
  March 1990
  Take the Mystery Out of the Switched-Capacitor Filter:
  The System Designer’s Filter Compendium
  Richard Markell
  INTRODUCTION
  Overview
  This Application Note presents guidelines for circuits utilizing Linear Technology’s switched-capacitor filter family.
  Although the switched-capacitor filter has been designed
  into “telecom” circuits for over 20 years, the newer devices are faster, quieter and lower in distortion. These
  filters now achieve total harmonic distortion (THD) below
  –76dB (LTC®1064-2), wideband noise below 55μVRMS
  (LTC1064-3), high frequency of operation (LTC1064-2,
  LTC1064-3 and LTC1064-4 to 100kHz) and steep roll-offs
  from passband to stopband (LTC1064-1: –72dB at 1.5 ×
  fCUTOFF). These specifications make the new generation of
  switched-capacitor filters from LTC candidates to replace
  all but the most esoteric of active RC filter designs.
  Application Note 40 takes the mystery from the design of
  high performance active filters using switched-capacitor
  filter integrated circuits. To help the designer get the highest performance available, this Note covers most of the
  problems prevalent in system level switched-capacitor
  filter design. The Note covers both tutorial filter material …
