Re: .MEAS Failure
Having just installed V24.1.4, I noticed that: .option measdgt=x ..appears to have been disabled, and doesn't appear to do anything now - the .MEAS time points are now always double precision. The log

Re: intuition behind a solution to crashing time domain simulation
#Time-step-too-small
Or it suggests that there is a problem with THAT circuit when combined with a very wide-bandwidth op-amp like the AD797 (not 757). The simple circuits I tried for the AD797 ran OK. The fact that your

Re: Ltspice alternative for AD797
Have you tried the product selection guides, which most IC vendors and many distributors offer on their websites? There probably is a reason.? It might be worth investigating why.? High-bandwidth

Re: Monitor simulation percent completion from python
I don't remember with certainty if this is true - but I believe the .TRAN command has numbers when you look at the expanded netlist.? In other words, the formulas have been evaluated.? That is true

Re: Estimating Base spreading resistance for a bipolar transistor via LTspice
When temperature increases, the current resulting from the reverse-biased gate-drain junction increases exponentially, so yes, noise increases with temperature.

Re: Estimating Base spreading resistance for a bipolar transistor via LTspice
I am wondering whether the noise at higher current values won't be affected by the warming of the device.? I know this to be a limiting affect for JFETs.

Re: Create symbols.
What version of LTspice are you using? The F1 key works on V17.1, V24.0 and V24.1. If you're using one of those and it doesn't work, your installation may be missing the help file. -- Regards, Tony
