Pinched hysteresis loops are a fingerprint of square law capacitors
نویسنده
چکیده
It has been claimed that pinched hysteresis curves are the fingerprint of memristors. This paper demonstrates that a linear resistor in parallel with a nonlinear, square law capacitor also produces pinched hysteresis curves. Spice simulations are performed examining the current vs. voltage behavior of this circuitry under different amplitudes and frequencies of an input signal. Based on this finding a more generalized dynamic systems model is suggested for ReRAM and neuromorphic modeling to cover a broader range of pinched hysteresis curves.

Comments on Pinched Hysteresis Loops of Memristive Elements
The hysteresis loops pinched in the v-i origin belong to well-known fingerprints of memristive elements driven by bipolar periodical signals. Some element properties follow from the loop behavior in the close neighborhood of the origin. The paper analyzes this behavior of the memristive elements that produce steady-state hysteresis loops under harmonic excitation. It is shown that there is a co...
متن کاملBiology of Memristor Minds
All 2-terminal non-volatile memory devices based on resistance switching are memristors, regardless of the device material and physical operating mechanisms. They all exhibit a distinctive “fingerprint” characterized by a pinched hysteresis loop confined to the first and the third quadrants of the v–i plane whose contour shape in general changes with both the amplitude and frequency of any peri...
متن کاملPinched hysteretic loops of ideal memristors, memcapacitors and meminductors must be ‘self-crossing’
Recently, novel findings have been published, according to which some mem-systems excited by harmonic signals can be characterised by the so-called ‘non-crossing-type pinched hysteretic loops’. Presented is a proof that this phenomenon cannot occur in ideal memristors, memcapacitors and meminductors which are defined axiomatically via the corresponding constitutive relations or via other equiva...
متن کاملResponse to “ Pinched Hysteresis Loops is the Fingerprint of Memristive Devices ”
This is a short response to a recent paper by Kim et al. [1] which correctly notes that the zerocrossing pinched hysteresis loop of a memristor or memristive system must hold for all amplitudes, for all frequencies, and for all initial conditions, of any periodic testing waveform, such as sinusoidal or triangular signals, which assumes both positive and negative values over each period of the w...
متن کاملPassive Fully Floating Emulator of Memristive Device for Laboratory Experiments
A simple emulator of memristive system, containing only passive electronic components, namely resistors, capacitor, and no-DC biased transistor is described. Unlike other hitherto published emulators it does not exploit DC power supply. Moreover, it provides effective emulation of grounded as well as floating memristive systems. The circuit idea enables interesting experiments, demonstrating th...
