Specific Aspects of high frequency Gm-C filters

  • Wim Dehaene

Abstract

This paper discusses typical problems encountered during the design of high frequency Gm-C filters. The first part handles the problem of parasitic singularities. The second part discusses tuning systems for HF Gm-C filters. The discussion is done with a a seventh order 0.05° equiripple on the phase low pass filter as an example.
