DC offsets in direct conversion multistandard wireless receivers: Modeling and cancellation
2006 (English)In: Analog Integrated Circuits and Signal Processing, ISSN 0925-1030, E-ISSN 1573-1979, Vol. 49, no 2, 123-130 p.Article in journal (Refereed) Published
Abstract [en]

To realize a high performance direct conversion receiver for multistandard wireless communications, the limiting factors in the direct conversion receiver should be identified and removed. In this paper, among many problems in direct conversion receivers, the DC offset problem is studied. The origins of the DC offset are summarized, and three self-mixing mechanisms generating the DC offset are modeled to better understand how the static (or time-invariant) and dynamic (or time-varying) DC offsets are produced from the mechanisms. A DC offset cancellation scheme consisting of a static DC offset canceller and a dynamic DC offset canceller is proposed and verified through simulations.
