The fundamental source of the limitation of the image rejection in these receivers is the imbalance between their in-phase (I) and quadrature (Q) channels, which becomes more problematic when the receivers are of wideband. Besides traditional methods, this book provides novel solutions to the problem, which falls into two broad types. The first type refers to new circuits that produce less I/Q imbalance. This includeshigh performance switched-capacitor Hilbert transformers and precise quadrature sampling circuits. The second type is to compensate the I/Q imbalance, which is possibly frequency-dependent, in digital domain by calibration or | | 出版日期 | Book 2003 | | 关键词 | CMOS; Modulation; Phase; Signal; Software; Software Radio; analog; communication; radio; simulation | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4757-3737-0 | | isbn_softcover | 978-1-4419-5349-0 | | isbn_ebook | 978-1-4757-3737-0Series ISSN 0893-3405 | | issn_series | 0893-3405 | | copyright | Springer-Verlag US 2003 |
