This is a circuit using an AND gate. The truth table for this gate is as follows: A B F 0 0 0 0 1 0 1 0 0 1 1 1 If you have input A as your 3V3, and input B as your signal, you can see that when your input is open circuit (not connected), due to the pull up resistor R1, you get a 1-1 condition on the AND gate. Looking at the truth table, this would give you a logic '1' output. You need a closed path, or closed circuit, to get electric current to flow.

Using the Spice Model in a Circuit. Now that the Spice model is in your library, there are a couple things you need to do. The first is make the circuit which will contain our part. For example, here is a simple half-wave rectifier I have tossed together. The next is to let LTspice know … For better or worse, LTspice treats two terminal components differently than components with three or more terminals. For components like resistors, capacitors, and inductors this can make it difficult to know what the current convention is prior to actually running a simulation (especially if components have been mirrored and/or rotated).
03/06/2011В В· guys, i have downloaded 3 different file types of MAX4173 from MAxim; macromodel > .FAM orcad library > .LIB test circuit > .CIR Now, how do i use these files so i can simulate it on LTSpice? LTspice only shows slow transition times of 2ns. What's going on here? 8 I have used a pure sine source in my schematic, but the output signal of my circuit looks slightly different from cycle to cycle. 9 How does one set the threshold and high/low voltages for LTspice's digital devices?
Importing External Device models into LTspice! This blog will tell you the procedure to import external device i.e. third party models into LTspice as well as the installation of LTspiceIV software.

This is a DC circuit and we are interested in the steady state voltages and currents. In SPICE language this is a “DC operating point” or “op pnt
Download the circuit in FIG 4: Op Amp Test Circuit . FIG 4 . Running this circuit shows the output falls from 1V at dc to 0.707V at about 2.77MHz. Now remove the LT6231 and replace it with a standard 5 terminal op amp. This is the 'opamp2' model in the Op Amps folder in LTspice. • Place this file where LTspice will look for it, preferably in the local directory (where you circuit file is saved) • Add generic opamp (opamp2) to your circuit • Right-click on the symbol to invoke Component Attribute Editor • Enter Value = LM741/NS (must match the first line in LM741.MOD file, which is not a comment, i.e. not

05/06/2006В В· AD names their subcircuit model files with the extension .cir. I assume you use schematics for your circuit. Then you have to make a symbol for the subcircuit in .the .cir file. Therefore you have to master how to use subcircuits and how to to generate symbols for them. Have luck. ;-) Best regards, Helmut PS: I use LTspice. Ltspice Netlist Every circuit contains a netlist. The netlist is an ASCII text file describing the circuit. The first line is always the title, and the other lines will contain node numbers and circuit descriptors for each component. The netlist can be displayed from the View Menu, SPICE netlist. The netlist for the simple dc circuit is shown
The cir file extension is associated with PSpice, a full-featured, native analog and mixed-signal circuit simulator, developed by Cadence Design Systems, Inc.. The cir … 2. To open a SPICE circuit file select Open > File. Drop down the Files of Type box and select Circuit Files (*.cir) to make the *.cir files visible. Move to folder where you saved your SPICE circuit (LPFILTER.CIR), click on the filename, then click on Open. Your SPICE circuit file will appear in a text editor window.
