Analog techniques for reliable organic circuit design on foil applied to an 18 dB single-stage differential amplifier

In this work we present design strategies for organic Vt-insensitive circuit design tailored to organic p-type transistor technology, and we demonstrate them by application on a single-stage differential amplifier. Specifically, to reduce the Vt-sensitivity, we implement common-mode feedback, bootstrapped gain enhancement, cascoding and backgate steering. The effectiveness of the design strategies is demonstrated by showing a single-stage amplifier performing with 18 dB gain and losing only 4 dB gain after several months of exposure to ambient environment.
