Student project: TX-to-RX leakage mitigation in radar for vital-sign detection

Vacature details


The radar receiver suffers from TX leakage due to its finite isolation. A novel TX-to-RX leakage cancellation technique are required to relax the LO phase noise and RX dynamic range requirements. This project focuses on designing the TX-to-RX leakage mitigation.

What you will do

In radar application, e.g. vital sign or occupancy detection, the transmitter (TX) and receiver (RX) operate simultaneously. The TX leakage from RX significantly increase the dynamic rage of the RX, complexity of the antenna and degrade the noise performance due to phase noise. A passive cancellation approach using three-port duplexer can separate the RX and TX paths and share a single antenna, while the active cancellation compensate the noise in the RX path. In this project, the TX-to-RX leakage issue for radar application will be studied, and the integrated circuits will be implemented.

In this project, three main goals will be implemented in advanced CMOS technology:

  • Passive approach to achieve a high isolated duplexer.
  • Active approach to achieve a high isolated duplexer.
  • Overall design for the duplexer and its verification.

Your tasks:

  • Literature studies on state-of-the-art wireless transceiver.
  • Understanding both analog and digital design methodologies.
  • RF basics.
  • Architecture study and proposal.
  • Circuit implementation.
  • Layout and post-layout simulation.
  • Tape-out and measurement.

What we will do for you

You will be part of a team with the mission to develop world-class ultra-low power transceivers, with a sub-mW power consumption. These are used
in advanced radio and radar systems. The team is internationally recognized as a center of excellence in the field of ultra-low power transceiver design. The
ULP Wireless Systems team, is part of a broader program on wireless sensor node technology and designs prototypes of new ICs and new electronic systems for
demonstration and transfer to industrial partners.

 Who are you

  • Msc student in Electrical Engineering. 
  • Good written and verbal English skills  
  • Motivated student eager to work independently and expand knowledge in the field.
  • Knowledge of designing CMOS circuits.
  • Good analytical skills.
