Unique Applications for the LTC1062 Lowpass Filter &mdash AN24
PDF, 587 Kb, File published: Sep 1, 1987
Highlights the LTC1062 as a lowpass filter in a phase lock loop. Describes how the loop's bandwidth can be increased and the VCO output jitter reduced when the LTC1062 is the loop filter. Compares it with a passive RC loop filter. Also discussed is the use of LTC1062 as simple bandpass and bandstop filter.

A Simple Method of Designing Order All Pole Bandpass Filters by Cascading 2nd Order Sections &mdash AN27A
PDF, 245 Kb, File published: Jun 23, 1988
Presents two methods of designing high quality switched capacitor bandpass filters. Both methods are intended to vastly simplify the mathematics involved in filter design by using tabular methods. The text assumed no filter design experience but allows high quality filters to be implemented by techniques not presented before in the literature. The designs are implemented by numerous examples using devices from LTC's Switched- Capacitor filter family: LTC1060, LTC1061, and LTC1064. Butterworth and Chebyshev bandpass filters are discussed.

INTRODUCTION DESIGNING BANDPASS FILTERS Filter design, be it active, passive, or switched capacitor,
is traditionally a mathematically intensive pursuit. There
are many architectures and design methods to choose
from. Two methods of high order bandpass filter design
are discussed herein. These methods allow the filter
designer to simplify the mathematical design process
and allow LTCвЂ™s switched capacitor filters (LTCВ®1059,
LTC1060, LTC1061,LTC1064) to be utilized as high quality
bandpass filters. Table 1 was developed to enable anyone to design Butterworth bandpass filters. We will discuss the tables in
more detail later in this paper, but letвЂ™s first design a filter. AN27A is the first of a series of application notes from
LTC concerning our universal filter family. Additional notes
in the series will discuss notch, lowpass and highpass
filters implemented with the universal switched capacitor
filter. An addition to this note will extend the treatment of
bandpass filters to the elliptic or Cauer forms.
This note will first present a finished design example and
proceed to present the design methodology, which relies on …
