  • SPICE Model of Memcapacitor

    Created by MicroCapDesigner, published on 02-10-2012

    generalizing the concept of memory devices to capacitor the memcapacitor is the device whose capacitance depends on the state and history of the system, furthermore this device can store energy. these memory devices can be used to model effectively natural phenomena down to the nanometer scale, because at the nanoscale the dynamical properties of electrons and ions strongly depend on the history of the system. This simulation models the Q-V hysteresis effects when the memcapacitor is driven with a sinusoidal voltage.

  • Capacitance Multiplier

    Created by TINADesigner, published on 14-12-2011

    A capacitance multiplier circuit is implemented with an operational amplifier opa725. The effective value of a small capacitor C1 is increased to a much larger value, The capacitance seen at Vout is: Cout = C1 * R1/R3. For C1=100pF, the resulting capacitance is 100nF. The output capacitance can be verified with the cutoff frequency of resulting R-C circuit, Fc= 1/(6.28*R*C) =1.59 Hz. Click here to run the simulation immediately with TINACloud.

  • Capacitance and Capacitive Reactance

    Created by Cribald, published on 18-01-2011

    This is a multiple schematics design that explains what is a Capacitance, a Capacitive Reactance, what are effects of increase or lowering a capacitance, how calculate parallel or series capacitances.
