Printed complementary organic thin film transistors based decoder for ferroelectric memory

This paper presents a decoder circuit manufactured in a printed complementary organic TFT technology on flexible substrate. Decoder architecture, simulation and experimental results are detailed. In order to comply with current printed electronic capability, a tree based decoding architecture is specifically implemented in order to provide robust functionality with a limited number of transistors. Two different output stages are implemented in order to drive active and passive ferroelectric memory. To drive active matrix, a buffer output stage is proposed, whereas a pass-gate based output stage, with customizable voltage, is used for passive matrix. Characterization results show that the decoder for both output stage options is functional for a wide range of voltage from 40V down to 5V, and for timing between 5ms and 100ms.
