SPICE Simulation Model of Meminductor
published on 20-10-2012
The meminductor as memristor and memcapacitor can be useful not only for non-volatile memory applications. These components are able to store information in a continuous fashion, they can acquire respectively a continuos set of inductance, resistance , capacitance values within certain bounds, so they can store analog information and can be useful even for analog circuits. This simulation models the hysteresis effects in the flux-current curves when meminductor is driven by a sinusoidal current

IIR Infinite Impulse Response 8-th order Digital Low Pass Filter
published on 12-10-2012
SPICE Simulation of a digital low pass filter IIR (with an impulse response function that is non zero over an infinite length of time). Amplitude frequency response and its impulse response are analyzed with coefficients filter quantized to 8 bits. The frequency response is very little sensitive to coefficient quantization due to the low values of quality factors of individual second order sections.

SPICE Model of Memcapacitor
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.

Simulation Model of Memristor from Hewlett-Packard Labs
published on 26-09-2012
non-linear passive two-terminal component where voltage and current are linked by a non linear relationship. its resistance changes based on past history, on the voltage the device has seen in the past. This simulation models the I-V hysteresis effects when the memristor is driven with a sinusoidal voltage. These devices are being developed for application in nanoelectronic memories.

NPN Transistors Double Balanced Mixer
published on 10-05-2012
This mixer is usable for frequencies around 500Mhz. Discrete transistors mixers require the matching of the transistors' characteristics. This issue is overcome by applying a bit of feedback through emitter resistors. The base are driven with LO signal from a balun transformer. This mixer exhibits a conversion loss of 6dB and 15 to 17dBm of LO drive power.
