Abstract This paper presents a realization of fractional-order Band pass-filter (FOBF) based on the concepts fractional order inductors and capacitors. The FOBF is designed implemented using both simulation hardware approaches. proposed filter considered up to second or less with any real positive number. One cases when ? ? 1 ? ? 1. In case, calculate optimal parameters, modified Particle Swarm...

The trend in next-generation switched-mode power supplies will lead to modular, scalable solutions which can deliver power efficiently over a wide range of operation. Multiple parallel power stages, often called “phases”, are necessary to meet these requirements. This paper details a new approach to introduce more control features like phase-alignment, current sharing and phase shedding, which ...

This paper presents a new general purpose accelerator based on the Kress ALU Array III (KrAA-III) a novel field programmable ALU array (FPAA), which efficiently supports high performance arithmetic computations by massive pipelining. The KrAA-III and its underlying concepts will be introduced as a generalization of systolic array structural principles illustrated by a simple real world computin...

The digital pulse width modulator (DPWM) is the crucial building block for digitally-controlled DC-DC switching converter, which converts the digital duty ratio signal into its analog counterpart to control the power MOSFET transistors on or off. With the increase of switching frequency of digitally-controlled DC-DC converter, the DPWM with higher time resolution is required. In this paper, a 1...

Abstract This paper describes a mixed-signal integrated circuit implemented in low-cost CMOS technology optimized for dc/dc and ac/dc converter applications. The device is partitioned into a hardware digital controller comprised of a digital signal processor (DSP) controller and an instructionbased microcontroller (MCU) system management processor section. The hardware digital controller includ...

Many early vision tasks require only 6 to 8 b of precision. For these applications, a special-purpose analog circuit is often a smaller, faster, and lower power solution than a general-purpose digital processor, but the analog chips lack the programmability of digital image processors. This paper presents a programmable mixed-signal array processor which combines the programmability of a digita...

Abstract – Following a short description of Field Programmable Analogue Arrays (FPAA), the implementation of specific equalising filters, using FPAA, will be presented. Special focus will be laid on the design and implementation of equalising filters for digital to analogue conversion, but the design program can solve a by far wider range of filter implementation problems. Included in the paper...

The paper deals with the problem of designing main FPGA-cell blocks with the current-mode gates – novel digital gates operating with constant, continuous power supply current. Using proposed approaches to designing digital current-mode circuits, the current-mode prototypes of several digital circuits and the Spartan II slice are designed. The obtained circuits are characterized by smaller hardw...
