Abstract

In this work an organic dual DC-DC up-converter and an organic 2-stage operational amplifier are presented, both implemented in a thin-film organic electronics technology on foil. The converter has a conversion ratio of 2.5 and only consumes 1 μA from a 15 V power supply voltage. The converter is designed for biasing gates and backgates of transistors in a p-type only technology and enables to bias both input and output nodes of a differential amplifier to the same DC voltage. This in turn enables to directly connect consecutive differential amplifier stages together. The latter is demonstrated through the 2-stage operational amplifier that has a measured gain of 20 dB and a gain-bandwidth product of 2 kHz. This opamp consumes 15 μA from a 15 V power supply.
