15 de fev. de 2004 · Hello.I have started to learn proteus and i designed a avr based schematic .But the simulation speed is very very low(0.000001 second/step).How can i increment simulation speed?
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.
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 · I won't give the exact speed because it is a function of the load capacity and even though I have a 16-bit LRC it may not be easy to measure accurately. Let me put it this way, if I compare the slope of the rising edge of the STM32F3 and the output of the 74HC04 at 3.3V, they are similar, with a 5.5V supply (74HC), the slope of the 74 is already a bit steeper.Compared purely optically on the ...
8 de ago. de 2008 · I am running simulation at 100 ps resolution for 5000 m sec but it take more than 30 hours to complete the simulation. Is there any way to speed up the Questasim simulation ?
11 de fev. de 2006 · speeding ADS hey, I'm doing a EM simulation of a PIFA with ADS, the overall size of the design is 110mmx25mm and the Er used is 2.2. it take more than 40min to do this (with a 2.2GHz 3GHz RAM), I know in IE3D it will take less time... can anyone help me speed up the simulation? (the mesh is 10...
27 de jun. de 2007 · If you want to meaure switching speed of a SPDT switch, you can use the R&S power sensor NRP-Z81 to capture the switching time. The smallest capture time can be 5ns. R&S have one PC power sensor software , the power sensor can connect with USB. Very easy to use.
7 de out. de 2001 · Speed to Torque I wonder something. For example; in a closed loop dc motor speed control, we obtain the torque reference by applying a PI or PID regulation to the speed profile. Then we obtain the torque producing reference current by the relation between the torque and the armature current...
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 ...
27 de jan. de 2012 · with variable speed that can be set with switches SW0 - SW7. The L298 Hbridge can be used. Care must be taken to protect the FPGA from excessive current draw and large voltage transients. Where do i start with writing the verilog code for this project. Thanks Guys
