I see you added a simple RLC series resonant circuit to represent a crystal.? Do you know that it is an appropriate model?? Does this oscillator circuit depend on series resonance, or parallel?? (I

@Andy /g/LTspice/photo/302220/3911798?p=Created%2C%2C%2C20%2C2%2C0%2C0 still do not show any oscillatory phenomenon after adding RLC between Q1 and Q2. See ck_osc.asc (

I met one of those, so I used the 'bullet' character ? as the decimal point in my report. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

I recommend not using numbers like ".002".? Leading decimal points are easily missed.? To my old eyes, it looked like you wrote "002" - until I squinted. Instead, use one of these: * 0.002 * 2m *

(1)? You do not need to add a library file.? It is included when you use its symbol. (2)? I just tried it, and it works great for me! So, what did you do wrong, that makes your simulation fail??

The 9095 is a quad. Are you using all four units or what? Why not upload your .ASC, so we can see what you are doing? -- This email has been checked for viruses by AVG antivirus software. www.avg.com

FWIW, the LT1017 comparator also works with simple substitution.? I have what I need for now, although I'm curious why the MAX9095 doesn't work.

Forgot to mention, in the transient analysis, the stop time is .002, so the graph displays two cycles.

*SUCCESS!* Thanks, guys, I got it working with Universal Op Amp 2.?? It's working as it should. I'm using simple transient analysis.?? The whole circuit consist of? one op amp and three voltage

I find that in many cases, the plotted variable does reach very small values, which are of no significance or interest, but Autorange accommodates them, as it should, having no 'knowledge' of which

For the life of me, I can not understand the purpose of "{{", no matter how hard I try. I get it if the formula was something like this: "... { { thing1 } + thing2 } ...". I do not understand when the

This is a good catch. From the posting in EZ, I was able to reproduce the problem. It appears that if you have "Generate Expanded Listing" ON and you use .savestate, you will see this error message in

I think it is clear - to me at least - that it is the intention, and the only thing that makes sense.? If you started with with or without curly braces anywhere in there, it seems clear that you want

Which op-amp did you use? LTspice's "opamp" is an unbounded ideal op-amp.? In the absence of feedback, its outputs could become indefinitely large, either positive or negative.? Perhaps they reach

In message <[email protected]>, Macrohenry via groups.io <macrohenry@...> writes Universal Opamp and Opamp 1 don't respect the power rails so the O/P will scale

Your description sounds confusing. You say 6V 1000Hz Sine wave, suggesting to me that you are running a ".AC"? analysis which is a "small signal" AC analysis, so you wont get an "output" which is a

I do not see a crystal on the schematic photo you uploaded ( /g/LTspice/photo/302220/3911530). I wonder if that schematic is supposed to be just the on-chip part of a circuit, where

In that photograph, which is a picture of a schematic drawn in a different program (not LTspice), it shows that the N-channel Source pins are lower down on the page.? ?That differs from how you drew

How can your be sure that that was the intention? -marcel
