15 de fev. de 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.
28 de dez. de 2011 · You need a high speed op amp with some current output capability (at least 100 mA). You also need to protect the varactor from inadvertent burn-out if forward biased. So there are two basic circuits: The single ended rail-to-rail op amp can not blow out the diode with a forward bias, so you can hook it up directly.
31 de jan. de 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.
12 de jun. de 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.
19 de abr. de 2006 · I am using 8051 microcontroller at this time for controlling the speed of the motor and this motor only has armature control.The speed will be set by entering the RPM through Keypad and speed would be control by Proportional Intergral controller, I will develop PI algorithm in the code, so I don't need to make extra analog circuit for this and ...
1 de jan. de 2011 · 7. Trophy points. 1,288. Location. Chandigarh, India. Activity points. 1,756. i am designing a laser receiver for detecting a rotating laser ( less than 1us pulse at 600meter), now am using reverse biased photo diodes as it gives highest speed due to low capacitance, but.
21 de mar. de 2008 · Hi all, I am using 90nm technology. After I use PLS and create the config view to do the simulation. In the AE, it is no problem that the ti run fast enough for just a few cells. After I want simulate the whole circuit, it because very small. In my circuit, there are 8 DFFs, 8 XOR and 16 Buffer...

11 de fev. de 2006 · 27. Trophy points. 1,308. Activity points. 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. R.
24 de jan. de 2008 · bldc motor speed calculation. measure the time between two transitions: ttr. it's the time it takes to go 60 electrical degrees (or 1/6 electrical period) electrical frequency = (1/6) / ttr. multiply by 2xpi to get rd/s. multiply by number of pole pairs (P) to get mechanical speed. multiply electrical frequency by 60xP to get RPM.
