A configurable direct delta-sigma converter for frequency division duplex (FDD) bands from 0.4 GHz to 3.6 GHz
This paper presents a novel design of 5th order direct delta-sigma receiver for multi-band multi-standard wireless applications. The receiver is designed to cover Frequency Division Duplex (FDD) bands from 0.4 GHz to 3.6 GHz with a configurable bandwidth of 3.84 MHz (WCDMA), and 9.0/13.5/18/37 MHz (LTE10M/15M/20M/37M) complying with 3GPP specifications.
