SUMMARY In this work we present a detailed study of the phase noise of subharmonic injection locked oscillators (sILOs). A new simple and efficient model has been presented for accurately predicting the phase noise of a microwave sILO. The validity of the analytical technique is verified with measurement results obtained from a 5-GHz fully differential(More)
A low-power, inductorless, UWB CMOS voltage controlled oscillator is designed in 0.18 µm CMOS technology targeting to a UWBFM transmitter application. The VCO is a DoubleCross Coupled Multivibrator and generates output frequencies ranging from 1.55 GHz to 2.4 GHz. A low-power frequency doubler based on a Gilbert cell, which operates in weak inversion,(More)
