Re: Creating a dirt-simple subcircuit component
I agree, and have tried but can¡¯t get it right! I want to link the symbol to ZeroOhm.asc in the same folder. Where/how to do that? In the symbol editor, Ctrl-A menu, right? In the Spice Model line?

Re: Creating a dirt-simple subcircuit component
I agree it's 'better', insofar as it really has zero resistance, but it makes the .ASC look very odd, especially it it's to be given to a user of the physical circuit. -- This email has been checked

Re: AC Analysis - show Mag in dBuV versus Freuqncy
Hi John, Please see my answer to items 1, 3, and 4. 1.* The intention was twofold, (a) to verify attention rate at -40dB/Dec and (b) to check filter behavior at higher frequencies* 2. I could get ?

Re: Creating a dirt-simple subcircuit component
You haven't given your subcircuit any properties. Just writing 0 ohms on doesn't work. It's much simpler to put in an ordinary resistor and give it the value 1?ohm (r even 1pohm). -- This email has

Re: Creating a dirt-simple subcircuit component
The Jumper symbol is a confusing one, to me at least.? I do not usually see that it actually separates nodenames, but it may allow them. Andy

Where is the sUbcircuit? I see a symbol, but not linked to any subcircuit.? That won't work. Andy

Creating a dirt-simple subcircuit component
I am trying to make a better Jumper: 1. The Lib Jumper does NOT separate net names (in VXVII, at least) 2. I'm stupidly missing *something* in creating a new device "Unknown subcircuit called in: xu1

creating gm/Id vs Id/W plot in ltspice
Hello ,I have created a two plots of Id vs Vgs and? d(Id)/d(Vgs) [also known as gm] vs Vgs as shown in the attached link. how can I create gm vs Id plot which unites the two? Thanks.

Add a voltage dependent voltage source to the output node and multiply it by 1meg.

Modify your source for an amplitude of 1u.All measurements will be referred to 1uV.

Re: AC Analysis - show Mag in dBuV versus Freuqncy
1. If you are only concerned with the response well below 1MHz, there is not much point in sweeping up to 10MHz. 2. You can't change the axis labels to dB?V within LTspice, but you can add text to

Hi John, Thanks for your response. fc of the first LC is 11.25kHz and that of the second one is 32.83kHz which are << 1MHz. I intend to show *dBuV* instead of *dB* on the vertical axis of the Bode
