To further decrease the power gain loss and noise figure of RF LNA circuit from the on-chip ESD protection circuit. A novel LC-tank RF ESD protection circuits is proposed in this paper and has been successfully verified in a 0.25-mum CMOS process with top thick metal. With the resonance of LC-tank, the LC-tank RF ESD protection circuit can reduce the power gain loss and noise figure at the operation frequency from ESD device. From the experimental results, the 4.5 circles inductor of LC-tank is the best choice for the requirement of 2kV HBM ESD level. The proposed LC-tank ESD protection circuit will be one of the most effective ESD protection solutions for RF circuits in higher frequency band (>10GHz).

High quality RF inductors, very low loss and noise CPW and microstrip lines, advanced broad and narrow band filters, and ring resonators have been achieved on Si substrates, using an optimized proton implantation process. The RF performance up to 100 GHz is close to that for ideal devices designed by EM simulation for lossless substrates.

According to the experimental results and practitioners' subjective experience, we report some hypotheses that may account for meditative phenomena during the practice of Zen-Buddhism. Orthodox Zen-Buddhist practitioners, aiming to prove the most original true-self, discover and uncover the inner energy or light on the way towards their goal. Perception of the inner light can be comprehended as resonance. Uncovering the inner energy optimizes physiological and mental health. In the meditation experiment, a significant correlation was observed between perception of the inner light and electroencephalographic (EEG) alpha blockage. We further examined this phenomenon by recording the EEG from subjects during a blessing that the subjects did not know being given. During the blessing period, significant alpha blocking was observed in experimental subjects who had been practicing meditation for years in preparation for being in resonance with the inner light. This report provides a new insight into the debate that meditation benefits our health.

Electrostatic discharge implantation to improve machine-model ESD robustness of stacked NMOS in mixed-voltage I/O interface circuits

A novel electrostatic discharge (TSD) implantation method is proposed to significantly improve machine-model (MM) ESD robustness of NMOS device in stacked configuration (stacked NMOS). By using this ESD implantation method, the ESD current is discharged far away from the surface channel of NMOS, therefore the stacked NMOS in the mixed-voltage I/O interface can sustain a much higher ESD level, especially under the MM ESD stress. The MM ESD robustness of the stacked NMOS with a device dimension of W/L=300mum/0.5 mum for each NMOS has been successfully improved from the original 358 V to become 491 V in a 0.25-mum CMOS process. This ESD implantation, method with the n-type impurity is fully process-compatible to general sub-quarter-micron CMOS processes.

In this work, we have investigated the effect of bismuth content on electrical properties of Sr0.8Bi2+xTa2O9+delta (SBT) thin films, obtained by using the metallorganic decomposition technique. The SBT precursor solution was prepared using high purity strontium acetate, bismuth acetate and tantalum ethoxide as the starting materials and acetic acid as the solvent. Thin films were deposited on Ir(50nm)/SiO2(100Mn)/Si substrates by spin coating with precise control of the solution viscosity and spin speed. As-deposited films were dried at 150degreesC for 10 min followed by pyrolysis at 400degreesC for 30 min in static air to remove the solvent and organic impurities. The films were then post-annealed at 650degreesC for 30 min in ambient oxygen atmosphere. The crystallinity of SBT thin films containing various bismuth levels was characterized by X-ray diffraction (XRD). The 30% Bi excess SBT thin films exhibited preferentially (115) oriented phase. The XRD pattern showed all major peaks corresponding to SBT phase. The microstructure, P-E hysteresis loops and leakage current of SBT films were found to be dependent on the bismuth content.

Type-2 fuzzy logic system (FLS) cascaded with neural network called type-2 fuzzy neural network (T2FNN), is presented in this paper to handle uncertainty with dynamical optimal learning. A T2FNN consists of type-2 fuzzy linguistic process as the antecedent part and the two-layer interval neural network as the consequent part. The dynamical optimal training algorithm for the two-layer consequent part of interval T2FNN is first developed The stable and optimal left and right learning rates for the interval neural network, in the sense of maximum error reduction, can be derived for each iteration in the training process. It can also be shown both learning rates can not be both negative. Excellent results are obtained for the truck backing-up control, which yield more improved performance than those using type-1 FNN.

We proposed the first threshold CQ signature scheme. The scheme is unforgeable and robust against any adaptive adversary if the base GQ signature scheme is unforgeable under the chosen message attack and computing the discrete logarithm modulo a safe prime is hard. Furthermore, our scheme can achieve optimal resilience by some modification.
