An ideal memristor with single-valued odd-symmetric charge-flux nonlinearity is extensively proposed for chaos-based applications. However, according to our boundary condition-based memristor model, the nonlinearity of a memristor nano-structure is in general multi-valued with strong dependence on input and initial conditions. Nevertheless, provided the model is augmented with suitable boundary conditions,...
In this paper, using of short-time chirp excitation for the bio-impedance measurement is discussed. The short-time chirp waveforms have at least two advantages. First, flat and wideband amplitude spectrum together with shortness of signal enable fast and adequate estimation of the object under study. Second, low power consumption with more than 90% concentration of the generated excitation energy...
We report an experimental technique for estimating the dispersion coefficient α of a constant phase element (CPE). The method employs using a setup to excite the impedance under consideration via a periodic triangle-wave current I(t). Measuring the 50% rise time of the developed voltage V (t) then enables finding α using a pre-calculated Table. Experimental results are shown.
Neuromorphic realizations of the short-term dynamics at a synapse often use simplistic circuit models. In this paper, we present a more biologically realistic VLSI implementation of these mechanisms. Our circuit approach is analytically derived from a model of neurotransmitter release, so that it can be directly related to simulation results and biological measurements. We present a reduced implementation...
