Abstract
In this work we present a fully integrated first order
continuous-time /1/6 ADC made in a pentacene-based dual-gate
organic thin-film transistor technology on flexible plastic foil. The
ADC achieves a precision of 26.5 dB at a clock speed of 500 Hz
and draws 100
A from a 15 V power supply. As sub-blocks of
the ADC, we also present a /86/116-insensitive single-stage differential
amplifier with 10 kHz GBW, a 3-stage operational amplifier, an in-
tegrator, a comparator and a level shifter. The circuits
