A high input impedance voltage mode universal biquad filter using two operational transconductance amplifiers (OTAs), one current feedback amplifier (CFA), two capacitors and one grounded resistor has been studied. The new circuit has three inputs and single output and can realize all the standard filter functions, that is low pass (LP), high pass (HP),(More)
Measurement of ψ(2S) meson production in pp collisions at √ s = 7 TeV Abstract The differential cross-section for the inclusive production of ψ(2S) mesons in pp collisions at √ s = 7 TeV has been measured with the LHCb detector. The data sample corresponds to an integrated luminosity of 36 pb −1. The ψ(2S) mesons are reconstructed in the decay channels(More)

Public Key Cryptosystems have been in use for more than three decades. A number of schemes based on integer factorization problem, discrete log problem, residuosity problem, digital signature methods, Lucas sequence, Lattice problems, error-correcting codes, braid groups etc. have been designed. Recently, Multivariate Quadratic (MQ) Polynomials could be(More)
The angular distributions and the partial branching fraction of the decay B0 → K*0 μ+ μ- are studied by using an integrated luminosity of 0.37  fb(-1) of data collected with the LHCb detector. The forward-backward asymmetry of the muons, A(FB), the fraction of longitudinal polarization, F(L), and the partial branching fraction dB/dq2 are determined as a(More)
A configuration of voltage mode (VM) multi-function biquad filters (MBF) is presented in this paper. The configuration (MBF) is implemented by using two OTAs (one dual output and other single output) and two capacitors. It realises all standard filtering functions i.e. low pass (LP), high pass (HP), band pass (BP), notch and all pass (AP). This(More)

Current conveyors are unity gain active elements exhibiting high linearity, wide dynamic range and high frequency performance than their voltage mode counterparts. The new current conveyor operating at low-voltage supplies high input impedance and low output impedance and consumes less power. In this study, a new low-voltage class AB second generation(More)

Cells of ten Candida strains were subjected to disruption using three methods-glass beads, sonicator and French pressure cell press separately and results compared for efficiency of each method. The French pressure cell press gave the highest protein yield and glass beads, the lowest (mean of means = 5.6, 40.0, 0.6 µg/ml, respectively, for the three(More)
Current mirror (CM) is the basic building block in analog and mixed mode circuit design. For high performance analog circuit applications, the current transfer ratio, output impedance and output swing are the most important parameters to determine the performance of the current mirror. CM's are important for analog integrated circuits because of their wide(More)
