QVCO with Complementary Coupling

Research output: Chapter in Book/Report/Conference proceedingChapter


Software-defined radio allows a single front-end to be used for multiple standards, through software programmability and reconfigurability. The original SDR, proposed by “Mitola”, has an ADC directly following the antenna, allowing all downconversion and post-processing to be performed in digital domain. This approach, in theory, would provide the highest level of flexibility and programmability. However, no practical implementation is possible with current technology. A more practical approach is to use a generic direct-conversion architecture with programmable filters as well as programmable LO to cover multiple bands.
