i am trying to design an application using ST25DV04K part. I am having trouble getting an antenna small enough to fit on my board. How do i make a small NFC antenna?

Denis,After working with eDesign Suite i found it has a bug in it. When you put in values they must have a leading zero in front of the number (For example it must be 0.2 not .2) So when you say add more turns it does not calculate properly if the ...

I have been testing with TDA7294 and need to switch to TDA7293. My test board works fine with the TDA7294 but when I put in a TDA7293 with no load and apply power to the device it draws massive amount of current. Can you tell me what i am doing wrong.

I have noticed the NFC tag sticker antenna's are quite small. Yet when I design and antenna using eDesignSuite it produces solution which are very large.
