Hallo.

I want to design a wireless receiver for low power applications.

For the front-end, it can be either an inductor to receive the power or a LC tank.

Could someone explain me how to select between these two?
It would be also very nice if you can provide me some literature for reference.

Hi katrin,

Can you some more details about your receiver, from the diagram, i guess its a implant. In such a case, mostly they are fixed frequency, so you have freedom to choose between both.


Its all depend on other constrains like size, cost, matching, noise performance, selectivity,tunablity...

Correct me if i m misleading.

thanks,

Thanks!

Yes, my receiver has a fixed working frequency for implants application

When both of the topologies are possible, could you please explain some details of these design constraints mentioned by you, such like size, cost, matching,..and so on?

to start with, u can refer to these books

1) Omnidirectional Inductive Powering for Biomedical Implants
2) CMOS Circuit Design for RF Sensors

it also points to several references..

Thanks,
