Diode Model Request for 1N5811 and 1N6628
Could someone let me know where I can find spice models for both 1N5811 and 1N6618? Thanks, Dan

Re: AD8336 failure
Hello Steve, Apologies for the earlier comment. I found your files in Files>Temp>AD8336, but there was no announcement or indication from you that they were there. You schematic wouldn't run, but not

Re: AC response
I know about time step control and its deviousness...! I think minimum time step size puts an u necessary computational burden when little or no activity is present.. it is better to have variable

Re: H-Bridge Controller Model
Andy, Assuming your PIC puts out a PWM signal, the simplest way to do this is to use 4 voltage controlled switches (SW). The front ends of the switches can be configured to switch on and off as

Re: .savebias command commented out
Hello Rick and All, Well, it seems to be operating properly now, in that the "Skip" file shows up, though the .savebias command is still commented out in the log file. I spent several hours yesterday

Re: H-Bridge Controller Model
I am in the process of designing a motor controller circuit. A PIC microcontroller will create/control a PWM signal which will be "inputted" to an H-bridge controller which will drive a brushed DC

Re: Simple model for diffin-diffout amp
You may want to look at Intersil's AN1556. See: <http://www.intersil.com/data/an/an1556.pdf> The author makes this claim about his method "Finally, Accurate SPICE Models I can Understand and Modify to

Re: H-Bridge Controller Model
amhtech, I don't know what you mean by "PWM input bidirectional h-bridge driver model.", but most drivers sink and source current. The power switches normally have reverse diodes, so, in effct they

Re: AD8336 failure
How on earth do you expect anyone to help you? You have not provided any files or a netlist to work with. By the way, your message says it is a warning, not an error - there is a difference. A warning

Re: Freqeucny Dependent resistor
Hi George, Laplace transform for ramp in increasing values is (1/s). Yuo search we for this. Since we have decreasing function hence inverse of previous case, you get (s). since s is complex no. with

Thanks Nice idea... This will work for transient analysis too, if LIST is supported in .tran.... Is list supported in .TRAN ?? This would allow you to have lot of data points during fast edges and few

Re: Sensitivity Anlysis..
Thanks. Interesting idea.. But it essentially wants me to double up my circuit on the schematic in order to get V(outref) ( the real circuit is not the voltage divider).. Further, V(Tol) has to be
