Abstract :
This paper describes a sheet-type scanner and its circuits. The three-dimensional-stacked sheets comprise of two organic-transistor sheets and one organic-photodiode sheet, which enable double-wordline and double-bitline structure. The operation was compared with the conventional single-wordline and single-bitline scheme, and confirmed by measurement. The double-wordline and double-bitline structure reduces the line delay and power by a factor of five and seven, respectively. A new dynamic decoder reduces active leakage current, to which the cut-and-paste customization can be applied
