LT spice error

On simulation, I am getting this error :



trouble converting to curly brace notation: mismatched single quotes in "K{(Uo*Cox/2)175.4-35.6uA/V^2"



My connections are correct. What might be wrong?


Just what it says. You are missing the closing curly brace.

I am a bit new to LTSpice. Is this some kind of installation error? I went through

and reinstalled but got the same error again.

Or is it because of some wrong way of simulation?

I get those all the time, ignore 'em, and go ahead and simulate the circuit.

Couldn't help it.

next time post MORE information, just guessing at several things:

if you erroneously use a function in LTspice it gives that curly brace error, too.

In other words, the 'form' looks right, everything is there, but it is totally wrong and the error message doesn't tell you where to look.

is this a function, or a parameter? where do you use it?

just not enough info to 'help' you.

click on the help at the top go to the users website and look for tutorials doing what you're doing.

Or, post more info here, might get some good answers.

K{(Uo*Cox/2)175.4-35.6uA/V^2 | ^-- This opening curly bracket has no matching closing curly bracket.

Also the "K" in front has no associated operator... aren't *'s always required for multiplication in LTspice? ...Jim Thompson

| 1962 | I love to cook with wine. Sometimes I even put it in the food.

Maybe the single quotes need to get married...

Those who are getting this error watch this video. It worked for me :

His accent is too thick to follow. I gave up.
