A New Highly Controllable and Accurate Algorithm for Defuzzifier Circuit Implementation

Defuzzifier circuit is one of the most important parts of fuzzy logic controllers that determine the output accuracy. The Center Of Gravity method (COG) is one of the most accurate methods that so far been presented for defuzzification. In this paper, a simple algorithm is presented to generate triangular output membership functions in the Mamdani method using the multiplier/divider circuit and...

A new circuit model for the Parameters in equations of low power Hodgkin-Huxley neuron cell

In this paper, α and β parameters and gating variables equations of Hodgkin-Huxley neuron cell have been studied. Gating variables show opening and closing rate of ion flow of calcium and potassium in neuron cell. Variable functions α and β, are exponential functions in terms of u potential that have been obtained by Hodgkin and Huxley experimentally to adjust the equations of neural cells. In ...

Statistical Characterization of Standard Cells for Variation Aware Delay Modeling

With the advance in CMOS VLSI circuit design through technology scaling, process variability has significantly increased uncertainties in the response of sub-45nm CMOS circuits. To address this challenge and obtain reliable fabricated chips, statistical timing analysis and library characterization tools have become significantly important. CPU-time intensive Monte Carlo (MC) simulations embedde...

Efficient Delay Characterization Method to Obtain the Output Waveform of Logic Gates Considering Glitches

Accurate delay calculation of circuit gates is very important in timing analysis of digital circuits. Waveform shapes on the input ports of logic gates should be considered, in the characterization phase of delay calculation, to obtain accurate gate delay values. Glitches and their temporal effect on circuit gate delays should be taken into account for this purpose. However, the explosive numbe...
