Abstract :
An improved phase noise model for an ultra wideband differential voltage controlled oscillator is proposed which accurately models the impact of tuning voltage on phase noise performance. A series of design examples are presented, which indicate that results from the proposed model agree strongly with transistor level simulations. The model has been further extended to single ended structures where further design examples indicate that accuracy is maintained.
