Existing techniques for bandpass filters ? an overview

Abstract

Existing techniques for bandpass filters are reviewed witha survey of classification of existing techniques for bandpass filters in both research and commercial products. Existing bandpass filters may be separated into off-chipandon-chipbandpassfilters. Asoff-chip filters are bulky and consume more power todriveexternal devices, the need forpossibleon-chipfilters for fully viable integrate dreceivers has increasingly been motivated. Techniques forpossible on-chip bandpass filters may be implemented using digital filters or analog filters.
