Optical and electronic devices for optoelectronic integrated circuits have been extensively studied, and now, more efforts for the conversion between optical and electrical signals are accordingly required. In this work, a silicon (Si)-compatible optically drivable III-V-on-Si metal-oxide-semiconductor field-effect transistor (MOSFET) is studied by simulation. The proposed optoelectronic device...

A fully integrated 5.8 GHz ETC transceiver LSI has been developed. The transceiver consists of LNA, down-conversion MIX, ASK detector, ASK modulator, DA VCO, and ∆Σ-fractional-N PLL. The features of the transceiver are integrated matching circuitry for LNA input and for DA output, ASK modulator with VGA for local signal control to avoid local leakage and to keep suitable modulation index, and L...

The front-end signal processing electronics for the drift-chambers of the Stanford Large Detector (SLD) at the Stanford Linear Collider is described. The system is implemented with printed-circuit boards which are shaped for direct mounting on the detector. Typically, a motherboard comprises 64 channels of transimpedance amplification and analog waveform sampling, A/D conversion, and associated...

The degree of automaticity of locomotion in primates compared with other mammals remains unclear. Here, we examine the possibility for activation of the spinal locomotor circuitry in noninjured humans by spinal electromagnetic stimulation (SEMS). SEMS (3 Hz and 1.3-1.82 tesla) at the T11-T12 vertebrae induced involuntary bilateral locomotor-like movements in the legs of individuals placed in a ...

neuroscience has recently contributed a lot to the understanding of aesthetic experience features. science, art and creativity are not really distinctively different entities. the parallelism seen between the properties of art and organizational principals of the brain has been highlighted through neuroaesthetic studies. aesthetic as a subjective experience has comprehensively been studies thro...

This paper describes flash ADC design using linearity improved threshold quantized comparator. Here, the need for a reference voltage generation network has been eliminated in a 4 bit flash ADC; with completely digital cell based comparators. Output generated from comparator called thermometer code is related mathematically with binary conversion. This conversion property is used for mathematic...
