A 0.4-6GHz LO Generation System Using a Dual-Mode VCO for Software-Defined Radio

摘要：

A wide tuning range LO generation architecture and its implementation for Software-Defined Radio (SDR) is presented. A continuous wide tuning range is achieved by using a dual mode VCO, a quadrature single sideband mixer and frequency dividers. The dual mode VCO can work either in a wideband mode or in a quadrature mode to support the proposed architecture. The circuit is implemented in TSMC 0.13 μm CMOS process. Post simulation results show that the generator achieves a 0.4-6GHz continuous tuning range with a FOMT ranging from -201.7～-204.5dBc/Hz.
