2
The four fundamental two-terminal circuit elements. O. Kavehei et al. Proc. R. Soc. A 2010;466:2175-2202 ©2010 by The Royal Society
3
Schematic of HP MR, where D is the device channel length and w is the length of the doped region. O. Kavehei et al. Proc. R. Soc. A 2010;466:2175-2202 ©2010 by The Royal Society
4
Two MRs in series: (a) with the same polarity, both η=−1 or both η=+1; (b) with opposite polarities, η=−1 and η=+1. O. Kavehei et al. Proc. R. Soc. A 2010;466:2175-2202 ©2010 by The Royal Society
5
The hysteresis of an MR based on equation (2.16). O. Kavehei et al. Proc. R. Soc. A 2010;466:2175-2202 ©2010 by The Royal Society
6
The hysteresis characteristics of the MR. It shows that the memristance value is varying from a very low to a very high resistance. O. Kavehei et al. Proc. R. Soc. A 2010;466:2175-2202 ©2010 by The Royal Society
7
The hysteresis characteristics using the nonlinear drift assumption. O. Kavehei et al. Proc. R. Soc. A 2010;466:2175-2202 ©2010 by The Royal Society
8
Nonlinear window functions, (a) F(x)=1−(2x−1)2p, (b) F(x)=1−(x− sgn(−i))2p. O. Kavehei et al. Proc. R. Soc. A 2010;466:2175-2202 ©2010 by The Royal Society
9
The SPICE macro-model of MR. Here, G, H and S are a VCCS, CCVS, and a switch (VON=−1.9 V and VOFF=−2 V), respectively. O. Kavehei et al. Proc. R. Soc. A 2010;466:2175-2202 ©2010 by The Royal Society
10
