A pixel output node of the image sensor is connected to the input gates of several neuron MOSFETs which are implemented on the periphery of the imaging area. The pixel output is weighted by the input gate's capacitance value and summed up on the floating gate. Thus the filter characteristic is determined by the input gates' capacitance values and the number of pixels connected to the input gate...

It is shown that while the mutual information curves for coded modulation (CM) and bit interleaved coded modulation (BICM) overlap in the case of a single input single output channel, the same is not true in multiple input multiple output (MIMO) channels. A method for mitigating fading in the presence of multiple transmit antennas, named coordinate interleaving (CI), is presented as a generaliz...

Harmonic pollution and low power factor in power systems caused by power converters have been a great concern. To overcome these problems several converter topologies and control schemes have been proposed in recent years. This paper is proposed to study the control techniques for such converters to improve the Power Factor (PF) and reduce total harmonic distortion (THD) in the input current wi...

this study was designed to find which one of the three different presentations, i.e. input, input-output, and output-input, will be more effective in iranian efl learners' vocabulary acquisitions. to this end, first 54 out of 64 female students, aged from 19 to 23 years, with an average of 21, were selected out of starter-level efl learners at the university of tarbiat moalem in bandar abb...

We have developed an amplifier which removes its "offset" as a natural part of its operation by modifying the charge on a floating gate. The charge on the floating gate is adapted by a combinat,ion of electron tunneling and hot-electron injection, resulting in a nonlinear high-pass filter with a cutoff frequency less than 1 Hz. We show experimental data from this autozeroing amplifier for vario...

This paper will present work on a recharged comparator using Semi Floating-Gate (SFG) MOS devices. The output voltage of a basic SFG MOS Comparator circuit is normally interleaved with a recharge voltage. This prohibit control of passgates, which requires binary control signals. An output buffer is introduced to allow the control of pass-gates and multiplexers (MUXs) beyond a single recharge cl...

This article presents a hybrid boost converter architecture for improving the efficiency of light-emitting diode (LED) drivers used in mobile applications. By cascading low-switching frequency time-interleaved series–parallel switched-capacitor (SC)-stage with an inductive-boost converter, we facilitate lower voltage-rated switches, thus significantly reducing switching losses. Charge-sharing l...

An approach to the analysis of large-signal stability of a Boost converter via the small-signal loop gains is presented. The large-signal stable region of the small-signal designed bilinear Boost converter is estimated in light of the Input-output stability concept. By doing so, the effects of small-signals on large-signal stability are revealed. The effectiveness of the presented approach is v...
