We propose a new technique to enhance the characteristics of CMOS/SET hybrid multi-valued logic (MVL) circuits in terms of their stability and performance. A complementary self-biasing method enables the SET/CMOS logic to operate perfectly well at high temperature in which the peak-to-valley current ratio of Coulomb oscillation severely decreases. The(More)
We fabricated a carbon nanotube (CNT)/ polydimethylsiloxane (PDMS) composite-based dry ECG electrode that can be readily connected to conventional ECG devices, and showed its long-term wearable monitoring capability and robustness to motion and sweat. While the dispersion of CNTs in PDMS is challenging, we optimized the process to disperse untreated CNTs(More)
In this work, a new approach for the statistical worst case of full-chip circuit performance and parametric yield prediction, using both the Modified-Principal Component Analysis (MPCA) and the Gradient Method (GM), is proposed and verified. This method enables designers not only to predict the standard deviations of circuit performances but also track the(More)
This study is to investigate factors that affect usage change in mobile data service (MDS). The central claim of this paper is that influencing forces of usage increase in MDS are different from those of usage decrease. We propose that information quality as the motivator (forces of usage increase) and system quality as the de-motivator (forces of usage(More)
In this paper, we propose a method for interconnecting soft polyimide (PI) electrodes using anisotropic conductive films (ACFs). Reliable and automated bonding was achieved through development of a desktop thermocompressive bonding device that could simultaneously deliver appropriate temperatures and pressures to the interconnection area. The bonding(More)
