Thanks Tony, my bad! you do need to use CNTL-right click to get the required menu -robert

Re: Caps smaller than 0.5 uF?
Hello Ken, That's probably for two reasons: because LTspice was/is primarily intended to evaluate switchmode power supply chips, capacitors appropriate to that application are supplied. The other

Re: Caps smaller than 0.5 uF?
If you need the extra info, then you probably already have a capacitor picked out. So use its datasheet to fill in the blanks. Otherwise just edit the value. -- Nick [Non-text portions of this message

Re: Including model with process corners for mosfets
<snip> </snip> Hello Robert, I think you mean ctrl-right-click. For the NMOS symbol, you don't get the component attribute editor unless you do this, you get the "choose new MOSFET" dialogue. For the

Re: Simple model for diffin-diffout amp
Hi AG, I would caution against using a simple E source based fully differential amp model. Usually G source with appropriate resistor results in a much better behaved model. I believe I suggested you

Caps smaller than 0.5 uF?
When I look in the list the smallest shown is 0.5uF. When putting together a schematic with smaller caps, eg. 470pF I don't know any of the info on them other than the value. I see that the ones in

Re: Including model with process corners for mosfets
Hi Tal, If you right click on the device, you should get the "component attribute editor" window the Prefix will be MN, change this to XN. The Value NMOS needs to be changed to match the subcircuit

Re: CD4060 and CA3130 spice models request
Hi KMR, I think the nearest you are going to get to a CD4060 LTspice model is by using a CD4020 which is similar to the CD4060 but the CD4020 has not got an attendant oscillator. You can remedy this

Re: CD4060 and CA3130 spice models request
Perhaps you should try a Pspice forum? This is a group for LTspice. I feel sure that if you looked in the Files section of the group site, you would probably find information that might help you.

Re: Starting LTspice GUI from script file loading .sch and .cir - Linux
Hello Axel, Running four instances of LTspice from a bash shell is not a problem, but I don't think it's possible to open two files at once, either in Windows or Linux, from the command line. I've
