| Keywords: | Low-Voltage Wideband Sigma-Delta Modulators |
| Publisher: | Institute of Electrical and Electronics Engineers |
| Description: | This work presents two novel topologies of
cascade ΣΔ modulators with unity signal transfer
function that avoid the need of digital filtering in the error cancellation logic. The combination of these two aspects make them highly tolerant to noise leakages, very robust to non-linearities of the circuitry and
especially suited for low-voltage implementations at low oversampling. Behavioral simulations are presented that demonstrate the higher efficiency of the proposed topologies compared to existing cascades intended for
wideband applications. This work has been supported by the Spanish Ministry of Science and Education (contract TEC2004-01752/MIC) and the Spanish Ministry of Industry, Tourism and Commerce (FIT-330100-2006-134 SPIRIT). Peer reviewed |
