Abstract :
This paper presents a class of continuous-time noise-shaping modulators whose noise transfer function (NTF) has a periodic number of zeroes, These modulators may be used to implement A/D converters for low-pass or band-pass signals. The modulators employ delay elements capacitors. The delay elements implementations are based on transmission lines
