What does LTspice mean?
analog electronic circuit simulator
LTspice is a SPICE-based analog electronic circuit simulator computer software, produced by semiconductor manufacturer Analog Devices (originally by Linear Technology). It is the most widely distributed and used SPICE software in the industry.
How do you name a node in LTspice?
Right click the label and type in your new name. Press F4 or the “label net” button (a box with an ‘A’ in it). Type in a name. Place the little dot over the wire or node and click.
What is spice model for Mosfet?
This subcircuit model is a SPICE model that represents characteristics close to those of an actual MOSFET by adding, to the MOSFET M1 serving as the base model, a feedback capacitance, gate resistance, body diode, and resistance that imparts the temperature characteristic of the on-resistance Ron.
What is LT spice used for?
LTspice® is Analog Devices’ high performance circuit simulation program, which allows you to draft, probe, and analyze the performance of your circuit design. LTspice contains an integrated schematic editor, waveform viewer, and advanced features that are easy to use once you learn some basic commands.
What is a spice directive?
From LTwiki-Wiki for LTspice. In LTspice a SPICE Directive is text placed onto the schematic that passes directly into the netlist. It may be entered either as a single line or as a block of several lines of text. Since ENTER closes the text edit box, a new line must be started by typing either ctrl-ENTER or ctrl-M.
What is DC operating point analysis?
DC Operating Point Analysis calculates the behavior of a circuit when a DC voltage or current is applied to it. The result of this analysis is generally referred as the bias point or quiescent point, Q-point. In most cases, the results of the DC Operating Point Analysis are intermediate values for further analysis.
How to create and work with symbols In LTspice?
LTspice: Creating and Working with Symbols. In LTspice you can create a symbol automatically in two situations; either you have a subcircuit definition in ASCII format at hand or you want to create a hierarchy with your own schematics which are building blocks for larger designs. Hierarchical schematic drafting in particular offers powerful…
Who is the manufacturer of LTspice SPICE simulator?
LTspice is freeware computer software implementing a SPICE simulator of electronic circuits, produced by semiconductor manufacturer Linear Technology (LTC), now part of Analog Devices.
Where to find intrinsic SPICE models In LTspice?
See option setting at LTspice -> Tools -> Control Panel -> Sym. & Lib. Search Paths. The text that describes intrinsic SPICE models can be placed directly on an LTspice schematic by using the spice directive .op button.
Can a suffix replace a decimal point in LTspice?
In LTspice, any suffix (left column) can replace the decimal point of a real number, a common format for printed schematics. For example, 4K7 represents 4700, 1u8 represents 0.0000018. Although LTspice was originally based upon Berkeley SPICE 3f5 source code, it no longer is, thus some of its features may create non-portable files.
