Low Noise Oscillator Design Using Impulse Sensitivity Functions
October 14 @ 11:00 am - 11:30 am
On October 14th, 11am, Dr. Scott Wedge will be giving a virtual lecture as part of the Silvaco User’s Global Event. Dr. Wedge is Chair of the AP, MTT, ED and CAS Chapters of the IEEE Foothill Section. Low Noise Oscillator Design Using Impulse Sensitivity Functions Abstract: A variety of circuit simulation approaches are useful in determining the steady-state behavior of oscillator and VCO circuits. SmartSpice transient analysis, with appropriate initial conditions, remains a valuable tool. The additional capabilities of steady-state harmonic balance and shooting Newton algorithms make possible very good predictions of oscillator waveforms, output spectrum, and frequency tunability. What has been more elusive and challenging for the designer is to have simulation results that give a practical understanding of how device noise will perturb their oscillators and create phase noise and jitter. In this presentation we discuss new capabilities available in SmartSpice RF to generate accurate impulse sensitivity functions (ISFs). These ISFs represent linear periodic time-varying descriptions of oscillator phase sensitivity to device noise and provide insights to the designer seeking the best noise performance possible.
