Introduction: Memristors in EasyEDA
Demonstrating the EasyEDA Memristor using the ngspice Memristor XSPICE element.
The memristor is a two-terminal resistor with memory, whose resistancedepends on the time integral of the voltage across its terminals. rmin andrmax provide the lower and upper limits of the resistance, rinit is itsstarting value (no voltage applied so far).
The voltage has to be above a threshold vt to become effective in changingthe resistance.
alpha and beta are two model parameters.
The memristor code model is derived from a SPICE subcircuit published in:
