31. Jan. 2024 · You need to apply voltage gain so that dV/dt out is over 5 times the 'leading edge' of the STM32. drive signal. A fast NPN transistor, with R//C emitter load, possibly in cascode with a higher voltage. drive transistor, can give you a fast output fall-time, and Baker-clamping the base to collector can get you.
15. Feb. 2004 · If you can post your source and dsn file we'll have a look. Typically this happens when you externally wire a crystal etc. - this introduces an extremely high speed oscillator which bottlenecks the simulation and is completely superfluous anyway. Clock frequency is specified as a property of the microcontroller device.
12. Juni 2004 · hspice speed up simulation Besides fast options, autostop can help you as well. In addition, increase step for transient, AC,DC will help when too small is not necessary. Of course employing multi-cpu and use multi-thread job can make simulation fast dramatically.
Lattice Semiconductor High-Speed PCB Design Considerations. 2 The disadvantage of this approach is an increase in the number of backplane nets and card port interfaces that may be needed. The single net connection between n cards, in a multi-point backplane, must be replaced with n(n-1) unidirectional point-to-point links. Each card must ...
This sounds as though you want to examine 5 seconds operation of a circuit running at 1 GHz. It's an example of mixing micro and macro events. It becomes mismatched and unwieldy in simulation. (It is not a problem with real electronics, of course.) Consider trying a longer timestep. Also try a slower switching rate in your simulated circuit.
11. Feb. 2006 · 2,986. Re: speeding ADS. Just go to the task manager and in processes tab pick proper and give to it max priority, also do not tale a lot of points to run. But of course you can do it with other 3D simulators and for sure they will be more faster (like HFSS, CST etc.) David. radha. R.
30. Juli 2004 · 120 vac fan speed controller. I have found a very useful, inexpensive, no problem, inductive load, 5 amp, AC fan control for the size motors under discussion. It is a single pole, fully variable rotary speed control from Ace Hardware model 5A-120 AC for ten dollars ($10). It fits inside of a standard electrical box.
19. Apr. 2006 · For 220V DC motor 5 HP, BT152 SCR will be suitable which has current rating of 15-20A as my motor need 16A. Mmmhhh I'm not sure, but remember that a motor can use 3 times the nominal current at startup. Maybe you need >48amps SCR's. You should check it before you buy them 'cause they're expensive.
As the demand for high-speed data transmission grows, the interface between high-speed ICs becomes critical in achieving high performance, low power, and good noise immunity. Three commonly used interfaces are PECL (positive-referenced emitter-coupled logic), LVDS (low-voltage differential signals), and CML (current mode logic).
6. Nov. 2011 · The files are HFSS14. i have tried looking into both the files.didn't seem to have any difference in the setup and mesh analysis.i have read some points on how to speed up the simulation process,long time ago.things like symmetry,defining materials properly and so on. cant seem to find the document,when needed.
