Abstract :
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 0.13μm 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.
