Low Noise Oscillator Design Using Impulse Sensitivity Functions
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.

Dr. Scott Wedge
Low Noise Oscillator Design Using Impulse Sensitivity Functions
Biography:
Scott Wedge spent his first decade in electronics as an AMS/RFIC design engineer for mobile, airborne, and satellite communications systems. His interests in developing better simulation & modeling solutions led him into the electronic design automation industry where he has made numerous contributions to many successful simulation tools at Keysight, Mentor, and Synopsys. Scott served as Principal Investigator on several DARPA funded projects aimed at advancing high-speed high-frequency mixed-domain simulation and design techniques. His current work with the Silvaco R&D team is to further enhance the RF and signal integrity analysis capabilities of SmartSpice and SmartSpice RF. Scott received his Ph.D. from the California Institute of Technology.
Agenda
The Silvaco User's Global Event begins at 9:00am.
