Practical Modeling of High Speed Channels Based on Datasheet Input

As Dave Dunham from Molex Corp. likes to say “When designing high speed serial links beyond 10 GB/s, everything matters“.  Part of that everything is accurate modeling of transmission line losses. It is important to model dielectric and conductor loss accurately.

Here is a very useful presentation with speaker notes on the topic of “Practical Modeling of High Speed Channels Based on Datasheet Input” presented by Bert Simonovich, Lamsim Enterprise Inc at EDICON 2017.

Here is the motivation of the methodology proposed:

As my friend Eric Bogatin often likes to say, Sometimes an OK answer NOW! is better than a good answer late.” As a high-speed signal integrity practitioner and backplane architect, I often have to come up with an answer sooner, rather than later because of the impact to time and cost to my clients. And that’s why I have been motivated over the last few years to research and develop a simple methodology to accurately determine parameters to feed into modern EDA tools .

Happy Designing…..!!!

This workshop is complimentary but requires prior registration to receive a formal invite.

Workshop Agenda:

Pre Layout SI

  • Designing VIAs for optimum High Speed performance
  • Controlled Impedance Line Design
  • Channel Simulation Basics
  • High Speed Serial Link Simulation
  • Batch Simulation
  • IBIS-AMI Simulation
  • Eye Optimization

Post Layout SI

  • BRD/ODB++ Layout Import in ADS
  • Post Layout SI Simulation with SIPro
  • Channel Simulation with Post Layout Data

If you are interested to attend the same, you can drop a mail with your complete contact details at “anurag_bhargava@keysight.com” or leave your details in the comment box….

Happy Designing…!!!

P.S. If we are not able to accommodate you for the 1st session due to capacity limit or you are not able to make it due to other engagements then we will surely accommodate you in one the future  sessions which are likely to happen shortly.

Thermal Effects, Power Integrity and Your PCB

Keysight Technologies has scheduled a free 1-hour webcast on Thermal Analysis of the PCB and its impact on Power Integrity performance.

WHY THIS WEBCAST IS IMPORTANT

Did you know that in addition to validating the electrical performance of the power integrity on your PCB, it is also crucial to perform a thermal validation as well? This webcast introduces the thermal aspects of power integrity in your PCB designs and why it is critical to consider them. To better understand a design’s power integrity from the thermal viewpoint, it provides a theoretical background for heat transfer and overview of the thermal analysis technologies. Finally, the webcast demonstrates the importance of performing thermal analysis on PCB designs by showing a practical PCB design example.

Date: 27th July 2017

Time: 01.00pm Eastern Daylight Time (10.30pm India Time)

Design High Q Power Harvesting Circuit Using ADS

The Internet of Things (IoT) fulfills a promise of a more efficient and connected world. But with dozens of devices per household, battery management must become wireless and autonomous. This problem is now being solved through power harvesting, which enables a circuit to power itself from energy in the environment.

Challenge:

  • Design a circuit to harvest enough power for IoT devices of the future and verify simulation results before committing to fabrication

Solution:

  • Explored the design space for optimum configuration using Keysight ADS Software
  • Transformed the voltage to overcome the Schottky diode junction voltage using a high Q quartz crystal resonator

Results:

  • Doubled the usable power
  • Improved conversion efficiency from < 10 to 22.6%
  • Verified a close match between simulation and measurement data

RF Impedance Matching using SMT Devices

Here is a wonderful tutorial video on how to perform RF Impedance matching by optimally selecting SMT devices (or in other words what we call as discrete components based matching network design). Performing matching network design is not that difficult once you know the fundamentals, however to design good impedance matching network by selecting the realistic/standard components values which are available in market or available in individual’s inventory is always the most challenging job during the design process.

This video outlines a very neat way of performing discrete component based matching network design we can restrict software to use values which are available in our inventory or readily available in the market. Thanks to Hee Soo Lee (Keysight Technologies) to create such a wonderful & insightful video to solve one of the big pain of RF designers..
