In AN12380-2.1.2 (page 5) the capacitance value is specified for the ntag5 ICs. This value is specified with an operational state.
What would be the definition of operational state in this context?
I know about the NFC Antenna tool, but the question here is more about the specific capacitance value according to "operational conditions" here, does operational conditions means the core(digital control unit) is powered or just the rf interface? What were the tests conditions to get that value?
There is such a description at the bottom of the fourth page of AN12380, the input capacitance depends on the applied chip voltage. So, specifies the operational state should be the voltage Vla-lb.
Thanks & Best Regards,
