Highly Linear 2,5-V CMOS ΣΔ Modulator for ADSL+
(Institute of Electrical and Electronics Engineers, 2004)
We present a 90-dB spurious-free dynamic range sigma–delta modulator (ΣΔM) for asymmetric digital subscriber line applications (both ADSL and ADSL+), with up to a 4.4-MS/s digital output rate. It uses a cascade (MASH) ...
