1. A smart card inlay comprising:
a card circuitry;
a capacitor having a first portion and a second portion;
an inductive antenna configured to (i) communicate wirelessly with a card terminal, and (ii) power the card circuitry via inductive coupling to the card terminal; and
a DC-DC converter having an input coupled to the inductive antenna and an output connectable to the card circuitry, wherein
the DC-DC converter is configured to receive an input power signal from the inductive antenna and convert the input power signal into an output power signal provided to the card circuitry,
the output power signal matches an operating current and/or operating voltage of the card circuitry, and
the DC-DC converter and the card circuitry are connected in series between the first portion and the second portion of the capacitor.
