Abstract :
A low cost configurable frequency synthesizer using miniaturized multi-band voltage controlled oscillators (VCOs) is presented. The reported approach allows flexibility to cover several wireless standards, exploiting the capabilities of concurrent multi-mode resonance features in compact size with reduced cost. The typical measured phase noise at 100 kHz offset for typical frequency band 4 to 8 GHz synthesizer is -80 dBc/Hz with settling time less than 5 mS.
