In this article, an LTspice model of a hypothetical ADxxxx device will be used to create an IBIS model. It is a single-input and single-output digital buffer with an enable pin. Thus, the resulting IBIS model will have two inputs (DIN1 and EN) and a three-state out...
Use LTspice’s nonlinear capacitor capabilities and a reasonable model.This article describes how LTspice® simulations can be used to account for the effect of voltage dependence, or DC bias, caused by the use of ceramic capacitors with even smaller a
The GLaplace component is used in SPICE to describe a frequency-dependent impedance or resistance. Each frequency-dependent element (Rvar1, Rvar2, Lvar) is modeled in LTspice using the GLaplace G2 voltage dependent current source. Creating the Model in LTspice Place components for all fixed ...
An example of a schematic entry program I used quite frequently is LTSpice XVII. It is from Analog Devices (formerly Linear Tech). It can run on Windows, MAC and Linux. Here's another bonus: It free! Additionally LTSpice is designed to simulate HW as a PSpice program. This ...
Once a series has been selected place the part into your circuit To select a value from the series right click on the inductor to open the Component Attribute Editor window Triple clickon the SpiceModel value which is “Coilcraft_Inductor” by default to get the dropdown menu of available va...
Spice model of PMOS power switch (Model drawn in LTspice, Source: Elizabeth Simon) Results of running the SPICE simulation (Source: Elizabeth Simon) As we can see, we started with a part that initially appeared to be overkill, and yet we ended up putting three of them in parallel to sha...
” I don’t know, that seems pretty unambiguous. It seems to me that the safety offered by FOSS code is only incrementally greater than that of proprietary. It’s not orders of magnitude. Indeed, you might be worse off if you place trust in FOSS when you shouldn’t. To use a ...
