imec - Design of a wireless powering system based on weak inductive coupling

At imec, Connected Health Solutions R&D

 

Project Description

Wireless powering techniques are showing their potential in powering sensors in places which are inaccessible to power cable connection. Inductive coupling is a very well-known technique to power devices and results practical mostly if the coupling factor is sufficiently large. On the other hand, when the coupling factor results too small, the transmitted power would need to increase over reasonable values or the received power results too little to allow the operations of the sensor. This project is targeted to allow functionality to the system for the minimum available power possible (target is few nW available). And also, the system should have a large dynamic range, allowing also to properly operate when hundreds of mW are available. The system should also be capable of reaching impedance matching (e.g. via MPPT algorithms). The project will include the design of the building blocks and the full system verification of the described wireless powering system. The project will end with the layout of the system and postlayout simulations.

 

Your Tasks

  • Design and verify in CADENCE the system architecture by placing ideal building blocks, documenting the performance obtained during simulations.
  • Substitute the idea building blocks (one by one) with real ones, trying to maintain almost not varied the performance, documenting the performance obtained during simulations.
  • Simulate the all system and verify its performance over corners, documenting the performance obtained during simulations.
  • Make the layout of the circuit and verify it via DRC, LVS and parasitic extraction

 

Your Profile

  • Analysis and synthesis of basic analog circuits.
  • Knowledge of the ADE-XL simulation environment.
  • Basic experience with analog layout.
  • Innovative mindset (excited when investigating something uncertain and risky).
  • Motivated student eager to work independently and expand knowledge in the field.
  • Good written and verbal English skills
