Putting the flex in flexible mobile wireless radios - A wideband continuous-time bandpass sigma-delta ADC for software radios
2006 (English)In: IEEE Circuits & Devices, ISSN 8755-3996, E-ISSN 1558-1888, ISSN 8755-3996, Vol. 22, no 6, 24-30 p.Article in journal (Refereed) Published
This article has provided a brief overview of the SigmaDelta ADC conversion technologies for SDRs. The wireless receiver challenges were identified, the ADC design considerations and SigmaDelta solutions were discussed, and a low-distortion CT BP SigmaDelta modulator architecture was presented. The article has shown that the proposed CT BP SigmaDelta modulator is suitable for implementing high-IF ADC, making possible the software radio in handhelds. The major challenges in implementing such a high-IF ADC are the power dissipation and the degree of configurability, programmability, and adaptability that can be achieved by applying digital tuning and adaptive calibration.
