Ultralow power transponder in thin film circuit technology on foil with sub − 1V operation voltage

An ultra low power (ULP) transponder chip (XPDR) with sub 1V operation voltage is demonstrated by organic complementary (CMOS) thin film circuits (TFTs) on foil. The lowest operation voltage of the XPDR is down to 0.55V with a data rate of 35 bits/second. The power consumption (P
_tot
) of the XPDR is 2.5 μW at V
_dd
of 0.9 V and is 16 μW at V
_dd
of 2 V. A commercial AAA battery is employed to power the XPDR with an estimated run-time of more than 20 years.
