Project Summary

This Senior Design Project is about simulation and to design customized high-Q inductors both for on-chip and off-chip applications. A customized “Wireless Power Transmission Inductor” which transmits appreciable amount of electrical power wirelessly at lower resonant frequency, with an excellent efficiency.

Project Objectives

Our objective is to design Customized high-performance Inductor for mWatts wireless power transfer over a distance of few mm. We modify the on-chip Inductor which previously designed by EDCAS for Biomedical implants and maintaining high efficiency and improving Quality factor at the 200MHz frequency while keeping the footprint small.

Project Implementation Method

The main implementation is the application of wireless power transfer through magnetic coupling and to design both TX and RX coils. In this project we also apply the method known as “Magnetic Beamforming”, which is the use of multiple transmitters (TXs) each with one coil can be applied to enhance the WPT performance by coherently combining the magnetic fields induced by all TX coils in a beam toward the receiver (RX) coil. By using a low resistivity silicon substrate, spiral inductors made by Aluminum show advantages in performance and size with respect to transmission lines, even at millimeter waves (mm-waves), Keep that in mind that Aluminum is one of the perfect candidate for super conductor in which we have almost zero internal resistance which exponentially increase the quality factor at lower temperature. However, these models need to be parametrized either from test-structure measurements or from electromagnetic (EM) simulations.

Benefits of the Project

The main benefits in this project is that we innovate it by shifting Q factor of the on-chip inductors from their typical frequency ranges (GHz) to frequency ranges suitable for WPT (MHz), this is acceptable frequency range in biomedical implants and is not hazardous for human health and since we are using lower frequency as compare to Ghz the temperature of IC will remain low. Further, we are going to use Beamforming which is a well-known technique for maximizing the power efficiency of a far-field wireless power transfer (WPT).

Technical Details of Final Deliverable

Our final deliverables are to design and fabricated the on-chip inductor and with keeping the small foot print and increasing the Quality factor of inductor by either reducing the internal resistance or increasing the Inductance. After that we have to do a DRC before fabricating our inductor on Chip then verify the measured and calculated parameters and transfer up to some milliwatts power on our test bench.
