| Popis: | International audience; Direct Delta-Sigma Receiver (DDSR) architecture has emerged as an attractive solution for flexible receivers. In this paper, a reconfigurable DDSR architecture for GSM/WCDMA/LTE standards is presented. A 4th-order DDSR with multi-bit quantizers and reconfigurable sampling frequency is adopted in the design. A maximum gain-control range of 18 dB is employed to respect the dynamic range specifications of the targeted standards. A noise figure of 2.5 dB and a -5 dBm out-of-band IIP3 (OOB-IIP3) are achieved in this design. |
