https://community.nxp.com/t5/NFC/MF1ICS50-add-external-power-supply/m-p/1227597#M8166 <P>Hello.&nbsp;MF1ICS50 chip is a passive NFC tag that is supposed to be connected to an antenna in parallel and draw power from the reader device EM field. I want to add an external power supply to it, effectively making it an "active" tag, thus boosting read range. Is it possible? Can somebody give me a circuit diagram or at least some hints? Perhaps using LM358 amplifier.</P> Sun, 07 Feb 2021 21:49:38 GMT plentypvp 2021-02-07T21:49:38Z https://community.nxp.com/t5/NFC/MF1ICS50-add-external-power-supply/m-p/1227597#M8166 <P>Hello.&nbsp;MF1ICS50 chip is a passive NFC tag that is supposed to be connected to an antenna in parallel and draw power from the reader device EM field.
