Summary

Timing-related problems associated with signal sources are one of the major bottlenecks in designing today’s highly complex systems. Over many decades, jitter has been extensively studied and utilized to characterize timing inaccuracies in both digital and analog systems. Conversely, phase noise has been exclusively used in RF systems to represent frequency or phase inaccuracy. For both timing and frequency sensitive systems, phase noise measurement is emerging to be the most accurate method of characterizing all types of signal sources (RF, analog or digital). This short course covers the fundamentals of phase noise and jitter, which ultimately set the limit to PLL performance in applications such as frequency synthesis, serial data communication and clock/data recovery. Simple techniques to model phase noise at the circuit component-level and relate it to the overall phase noise and jitter performance of PLLs are presented. The course will also provide a detailed analysis of the different phase noise measurement techniques along with in-depth noise floor analysis. The focus throughout this course will be on providing practical measures utilizing numerous real life examples. This class is typically offered in three 2-hour sessions (9:00am to 11:00am Pacific time) via web-classroom. Each daily session is a live online event but the recording can be made available on demand and online to support students requiring a more convenient viewing time. For on demand students, simply register online or by contacting the office and you will receive the login details for 30 day access to the recording. Please contact the office for details at info@besserassociates.com.

This course is intended for registered individual students only. Please contact us for group rates at info@besserassociates.com or 650-949-3300. Recording, copying, or re-transmission of classroom material is prohibited.

Students will receive a signed Certificate of Completion on request.
