Realization of Programmable Switched-Current Differentiating Matrix for Signal Filtration Purposes

Abstract

The paper presents design of analog programmable switched-current matrix, based on second generation differentiators. The matrix is a part of mixed-signal ASIC, capable of FM frequency range signals receiving and decoding as well as complex processing of audio frequency signals [Il.Presented filter solution acts as a programmable matrix working with analog signal amplitudes but with discrete timing.
