Organic Linear Voltage-Controlled-Oscillator and Linear Current-Controlled Ramp-Generator on Foil

 A voltage-controlled delay cell is proposed. Two voltage-controlled oscillator architectures are fabricated based on the proposed delay cell. Measurement results emonstrate a linearity error of 0.1 %, considerably lower power-delay-product, and a smaller circuit area compared to the state-of-the-art VCO implementations in Organic thin-film-transistor technologies. A current-controlled ramp-generator circuit is proposed, which is the first of its kind implemented in flexible thin-film-technologies. The measurement results show a linearity error of 0.02 % for the ramp-generator circuit. All circuits are fabricated in Organic thin-film-transistor technology on plastic foil.
