TITLE: A Full-Wave Bridge Rectifier Based on Amorphous Silicon Schottky Diodes for Integration with Inductively Coupled Links on Plastic

ABSTRACT BODY: As large area electronic (LAE) systems incorporate increased functionality, it is desirable to transmit signals between adjacent plastic electronic sheets through near-field wireless coupling based on inductors and capacitors. Eliminating wired contacts can enable increased system scaling and reduced assembly complexity, but it can also be energy efficient due to the minimal wireless range needed. Near-field wireless coupling requires AC signals, which in turn leads to the need for a rectifier circuit, capable of efficiently converting control and data signals to DC. In this paper we describe: 1) an a-Si Schottky barrier diode, which is optimized to give a low voltage drop and operate at the relatively high frequencies (in the range of 100 kHz) required to improve the efficiency of the inductive links; 2) the integration of these diodes to form a full-wave bridge rectifier with an AC-to-DC power conversion efficiency (PCE), ranging from approximately 46 % at 200 Hz to greater than 10 % at 1 MHz; 3) a model for transient operation of these components and circuits, enabling the critical device factors as a function of frequency to be identified; 4) the demonstration of the rectifier circuit wirelessly receiving signals from an inductive link to provide DC control outputs to a TFT logic circuit.
