Analysis and Characterization of VCO for UWB Application
In recent years, the design of voltage controlled oscillators has become the subject of extensive research. Due to increasing demands for reconfigurable communication systems such as the Software Defined Radio (SDR), new wideband VCO architectures are required. This paper presents a wideband voltage controlled oscillator topology based on an active inductor generating negative resistance. The proposed architecture covers a frequency band between 5.47 GHz to 6.62GHz with phase noise of -113.7 dBc/Hz at 1MHz offset from the 5.7GHz carrier frequency.
