imec - Highly efficient wideband transmitter for implantable applications

At imec, circuits4IoT

In certain implantable applications, a low-power and wideband RF transmitter is needed for information transfer to the outside world. The project is about designing an optimal transmitter for implantable applications.


Project Description

Implantable sensors enable the sensing of parameters inside the human body, e.g., endoscopy imaging. This gives a world of information about the human body that cannot be obtained with external sensors. Connecting these sensors with a wire poses a risk for the body, such as infections. Therefore, wireless data transfer is crucial.


These implantable sensors need a transmitter for information transfer to the outside world. Because of the limited size, the battery is very small or even absent. Hence, the transmitter needs to be extremely efficient.


This project is aimed at evaluating different transmitter topologies for implantable sensors. One of the possible topologies is the I/Q sharing topology. It has recently gained a lot of attention and has attractive characteristics such as high bandwidth and high efficiency.
