Specific Aspects of high frequency Gm-C filtersThis 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.

ADSL CODEC Architecture that Minimizes DSP Computational Burdenristics of subscriber loops, the echo return loss of typical hybrid networks and the duplexing method employed. The architecture proposed here is based upon oversampled data converters. It relies on digital filters for standards compliance and minimizes analog filters.
