Ohm’s law is valid at low and intermediate electric fields < 10 4 Parameter Sweeps in LTSpice Parameter sweeps can be a useful tool to examine how circuit operation changes with variation in different passive values, source amplitudes, operating frequency, or any other parameter. To examine how to do a parameter sweep, we will consider a simple R-C circuit: R-C circuit used as an example

So, just like human languages post-Babel, translators came in. ADS has a part called (you guessed it) "netlist translator" or nettrans. If you have a PSPICE/LTspice netlist model that consists of open, basic components such as RLC, VCCS, industry-standard models and so on, then we can import it.

Set the Hold Off to 2 (mSec). Adjust the time base until you have at approximately two cycles of the sine wave on the display grid. From the Meas CA drop down menu select P-P under CA-V and do the same for CB. Also from the Meas CA menu select A-B Phase. 4. Vary the frequency of the sinewave on the AWG A menu from 500 Hz to 2.5 KHz in 100 Hz steps.

LTspice is a circuit simulator based on the SPICE simulator and available as a free download from Linear Technology (www.linear.com). LTspice is the most popular freeware SPICE simulator.

Just wanted to thank you for a great introduction to LTspice on Mac. It's still an awkward interface IMHO, but after following your tutorial here it makes a bit more sense now. I'm sure you're busy, but perhaps consider another tutorial showing how useful the `.meas` directive in LTspice can be.

However, in the Windows version, if I right-click in the waveform window, one of the choices there is File, and in that sub-menu there is a choice to Execute .MEAS Script. Take a look and see if the Mac version has that option too. If it doesn't, you could make a suggestion to the LTspice team to add that feature to the Mac version. Andy

I am trying to meas the exact phase margin using a.meas statement.meas ac res4 FIND ph (V (out)/V (in,out)) when mag (V (out)/V (in,out))=1 This tells LTspice to create a variable called 'res4' whose result is the phase of the open loop gain when the magnitude of the open loop gain is 0dB. The result is the following: Hello, my problem it's a bit complicated. I want to measure the magnitude (in dB) of the bode plot of a specific frequency after an AC analysis.

First-principles calculations are presented for Si, Ge, Sn doping of LiGaO 2.Both Si and Ge are found to be shallow donors. Sn is found to be a somewhat deeper donor. The site preference is studied and all three group-IV dopants are found to favor the Ga over the Li site when the Fermi level is in the upper part of the gap, corresponding to n-type doping and for Li-rich growth conditions.
