DC-DC Converters: Understanding & Controlling Conducted Emissions

I recently made a presentation about Understanding & Controlling Conducted Emissions while designing DC-DC Converters during Keysight India 2017 EEsof Design Forum and here is the recording of the same. Hope you will find it useful for your applications.

Don’t forget to offer your comments & valuable feedback after watching the video:

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…..!!!

Workshop on High Speed Signal Integrity

I would be conducting a day-long, hands-on workshop on High Speed Signal Integrity design at Keysight Technologies, Bangalore office. First session is scheduled on 17th August 2017.

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
