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..

Practical Impedance Matching Network Design

This short tutorial video explains the key steps to followed for a distributed matching network design taking Zin & Zout information from a Cree (Wolfspeed) GaN transistor datasheet.

We start the matching network design using ideal transmission lines in Interactive Smith Chart tool in ADS which then is converted to the equivalent microstrip line based network. We then optimize the matching network components to nullify the effects cause practical microstrip lines and junctions. Finally layout is generated and EM simulation is performed for more accuracy.

Parametric EM Simulations in ADS

This short tutorial video explains simple step to create parametric layout component in ADS. We then will learn how to run a parametric EM simulations which is pretty simple to do in ADS.

Eye Diagram Optimization

Eye Diagram analysis is one of the most commonly used analysis during Pre or Post Layout Signal Integrity simulations.

This short tutorial video explains simple to use steps of performing optimization of key Eye diagram parameters such as Eye Height giving lot of freedom to High Speed designers to tweak their designs.

Also, use of marker slider is explained which can significantly simplify the job of plotting eye diagram for each swept variable after we perform Parameter Sweep or Batch simulation on our pre- or post- layout board designs.
