Flexible electronic devices, such as the typical thin-film transistors, are widely adopted in the area of sensors, displayers, wearable equipment, and such large-area applications, for their features of bending and stretching; additionally, in some applications of lower-resolution data converters recently, where a trend appears that implementing more parts of system with flexible devices to realize the fully flexible system. Nevertheless, relatively fewer works on the computation parts with flexible electronic devices are reported, due to their poor carrier mobility, which blocks the way to realize the fully flexible systems with uniform manufacturing process. In this paper, a novel circuit architecture for image processing accelerator using Oxide Thin-film transistor (TFT), which could realize real-time image pre-processing and classification in the analog domain, is proposed, where the performance and fault-tolerance of image signal processing is exploited. All of the computation is done in the analog signal domain and no clock signal is needed. Therefore, certain weaknesses of flexible electronic devices, such as low carrier mobility, could be remedied dramatically. In this paper, Simulations based on Oxide TFT device model have demonstrated that the flexible computing parts could perform 5 × 5 Gaussian convolution operation at a speed of 3.3 MOPS/s with the energy efficiency of 1.83 TOPS/J, and realize image classification at a speed of 10 k fps, with the energy efficiency of 5.25 GOPS/J, which means that the potential applications to realize real-time computing parts of complex algorithms with flexible electronic devices, as well as the future fully flexible systems containing sensors, data converters, energy suppliers, and real-time signal processing modules, all with flexible devices.

This paper summarizes the recent fabrication and characterizations of flexible high-speed radio frequency (RF) transistors, PIN-diode single-pole single-throw switches, as well as flexible inductors and capacitors, based on single-crystalline Si nanomembranes transferred on polyethylene terephthalate substrates. Flexible thin-film transistors (TFTs) on plastic substrates have reached RF operation speed with a record cut-off/maximum oscillation frequency (f T /f max ) values of 3.8/12 GHz. PIN diode switches exhibit excellent ON/OFF behaviors at high RF frequencies. Flexible inductors and capacitors compatible with high-speed TFT fabrication show resonance frequencies (f res ) up to 9.1 and 13.5 GHz, respectively. Robust mechanical characteristics were also demonstrated with these high-frequency passives components.Keywords: flexible electronics; nanomembrane; radio frequency thin-film transistors; RF switches; inductors and capacitors IntroductionTraditionally, flexible electronics are mostly based on organic or low temperature deposition compatible amorphous semiconductor (Si) materials. Devices made from these materials can only be operated at very low speed (<<1 GHz) because of the inferior carrier properties of these materials. Regardless of the low speed, these flexible electronics are suitable for applications in products such as flexible displays [1], electronic tags [2], etc. In these applications, the mechanical flexibility of electronics is of critical importance. On the other hand, a number of other applications do require the use of extremely highspeed devices (>1 GHz, the radio frequency (RF) speed), such as Wi-Fi devices, wearable radios, RF identification devices, foldable phased-array antennas, large-area radars for remote sensing, surveillance [3], etc. Nonetheless, current high-speed devices have been predominantly made of rigid chips and none of the traditional flexible active semiconductors can satisfy the requirements of high-speed applications.A promising solution toward high-speed flexible electronics has emerged with the recent development of transferrable single-crystal Si nanomembranes (SiNMs) [4][5][6][7]. By releasing high-quality flexible materials from silicon-on-insulator (SOI) and other types of substrates and transferring them to a new host substrate, high carrier mobility comparable with that of the bulk counterpart has been demonstrated [5].

“…Recently, many types of interesting approaches have been actively researched and developed. Flexible displays (Gelinck & Leeuw, 2004;Park J. S. et al, 2009), radio-frequency flexible identification tags (Forrest, 2004;Jung M. et al, 2010), flexible and stretchable sensor arrays (Lin K. & Jain, 2009;Someya et al, 2005), flexible electronic circuit systems (Graz & Lacour, 2009;Zschieschang et al, 2010), stretchable lightings (Sekitani et al, 2009a), printable devices (Ishida et al, 2010), and sheet-type communication and power-transmission system (Sekitani et al, 2009b) are the feasible examples. In order to develop the practical systems using these devices, an embeddable nonvolatile memory is strongly required as one of the core devices.…”
