Realisation scheme of a linear voltage controlled quadrature oscillator (LVCQO) using the new second generation conveyor (VCII) is proposed. The topology utilizes pair matched analog multiplier devices coupled appropriately with VCII, as active building block (ABB). oscillation frequency (fo) linearly tunable by control (V); experimental verification exhibits tuning-range upto fo∼10MHz measured...

In digital signal processors multipliers play a major role because, high multiplication process is carried out in hardware part in digital circuits. Array multiplier also requires less space for implementation in ICs and is an efficient way of multiplication in digital integrated circuits [3-4]. In this paper we have designed and analysed a four bit array multiplier using 45nm CMOS process. Arr...

We study simultaneous block-diagonalization of cyclic d-tuples of commuting matrices. Some application to ideal projectors are also presented. In particular we extend Hans Stetter’s theorem characterizing Lagrange projectors. 1 Introduction Let V be a …nite-dimensional space over complex …eld C and let L := (L1; :::; Ld) be a d-tuple of pairwise commuting operators on V . Every polynomial p(x1;...

A ground-to-air free-space optical link is studied for a hovering unmanned aerial vehicle (UAV) having multiple rotors. For this UAV, four-quadrant array of photodetectors used at the receiver to alleviate adverse effect fluctuations by enlarging field-of-view. Extensive mathematical analysis conducted evaluate beam tracking performance under random effects fluctuations. The accuracy derived an...

In this paper, a four-quadrant Riemann problem for 2×2 system of hyperbolic conservation laws is considered in the case delta shock appearing at initial discontinuity. We also remove restriction that there only one planar wave each include existence two elementary waves discontinuity and classify 14 topologically distinct solutions. For case, we construct an analytic solution compute numerical ...

Cascadable, CMOS synapse chips containing a cross-bar array of 32x32 (1024) programmable synapses have been fabricated as "building blocks" for fully parallel implementation of neural networks. The synapses are based on a hybrid digital-analog design which utilizes on-Chip 7-bit data latches to store quantized weights and two-quadrant multiplying DAC's to compute weighted outputs. The synapses ...
