Abstract :
A novel approach for a monolithic Codec Filter is presented, which provides results for the dynamic range and the signal-to-noise ratio which exceed the CCITT requirements considerably and in addition offers very comfortable programming possibilities. Progress in circuit design simulation techniques and advanced CMOS technology made it possible to integrate the analog part and the fully digital, programmable signal processor on a single chip in an economic way. Compared to conventional Codec Filter circuits, the presented solution may further profit from the continuing reduction in feature size of VLSI technology in terms of power consumption and chip area.
