Continuous-time cascaded ΣΔ modulators for VDSL: A comparative study
(The International Society for Optical Engineering - SPIE, 2005)
This paper describes new cascaded continuous-time ΣΔ modulators intended to cope with very high-rate digital subscriber line specifications, i.e 12-bit resolution within a 20-MHz signal bandwidth. These modulators have ...

A new high-level synthesis methodology of cascaded continuous-time ΣΔ modulators
(Institute of Electrical and Electronics Engineers, 2006)
This brief presents an efficient method for synthesizing cascaded sigma–delta modulators implemented with continuous-time circuits. It is based on the direct synthesis of the whole cascaded architecture in the continuous-time ...
