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 http://www.electronicspoint.com/threads/ltspive-iv-probs.252963/ 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.

^-- 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?

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 : https://www.youtube.com/watch?v=ez8waA9whNk&t=2s.

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