Abstract
The implementation of a completely monolithic channel filter containing all frequency selective functions associated with a PCM line interface is described. The circuit utilizes switched capacitor techniques. Design of the overall architecture, the individual filter sections, and the operational amplifiers in NMOS technology is described. Experimental results are presented.Keywords
