A 10 MHz Bandwidth, 70 dB SNDR Continuous Time Delta-Sigma Modulator With Digitally Improved Reconfigurable Blocker Rejection.

This paper presents a continuous-time third-order low-pass delta-sigma modulator (DSM) with digitally enhanced out-of-band (OOB) signal filtering for enhanced blocker rejection in receiver analog-to-digital converters (ADCs). It is well known that strong OOB interferers define the required dynamic range (DR) of a receiver. Usually, a channel-select filter (CSF) is therefore required, together with...
