Spectre RF Analysis using Shooting Newton Method

Length: 2 days (16 Hours)

Course Description

In this Engineer Explorer course for RF designers, you gain advanced knowledge of RF circuit analysis. This course explores applications of the Shooting Newton engine used for RF analyses in the Virtuoso^® Spectre^® RF circuit simulator environment. You learn simulation setup methods of various analyses pertaining to commonly used RF circuits to simulate periodic operating points, transients, and RF envelopes. You evaluate noise, stability, and parameters, such as IP3, in detail. You also examine the simulation solver with an emphasis on the parameters and convergence aids that help optimize and speed up the simulation while analyzing large RF circuits. PSS, QPSS, Periodic Noise Analysis and S-Parameter analysis are some of the topics that are discussed.

Learning Objectives

After completing this course, you will be able to:

• Apply the periodic steady-state (PSS) analysis algorithm, its options, and its properties to simulate and analyze RF circuits
• Use and apply the quasi-periodic steady state (QPSS) analysis algorithm, its options, and its properties
• Apply simulator accelerators and convergence aids to maximize efficiency in RF simulations
• Use the linear periodic time varying (LPTV) algorithms and apply the periodic AC (PAC) and periodic transfer (PXF) analyses
• Perform periodic S-Parameter (PSP) and periodic stability (PSTAB) analysis on LPTV circuits
• Perform periodic noise analysis (Pnoise) and create noise summary tables, and understand how to differentiate between noise coming from the noise source and that coming through the periodic transfer function using the noise separation feature
• Apply the periodic noise analysis (Pnoise) to define and evaluate different types of jitter in driven and autonomous circuits, such as oscillators
• Evaluate the period (Jc) and adjacent period (cycle-to-cycle Jcc) jitter, evaluate jitter for driven circuits (Jee) and also measure digital jitter with an eye diagram
• Simulate voltage controlled oscillators (VCOs) and use the periodic stability (Pstab) analysis on the oscillator
• Extract S-Parameters and simulate an S-Parameter file
