Abstract

This paper presents a latched comparator designed in a double-gate p-type-only organic thin film transistors (OTFTs) technology. The circuit is tailored to take the maximum advantage of the features of the double-gate technology, which allows an input capacitance of only ~35fF. The measured single stage-latch reaches rail-to-rail logic levels with less than 100mV differential input signal and about 10V input common mode range for V_DD=20V. The DC small-signal gain is larger than 46dB and the static power dissipation is ~30nW. All measurements were taken in air and in daylight.
