I have been useing the chepeast version of pads from mentor. Now I need a more expensive version because of limiting in the current version.
The cheapeas version pads from mentor costs: 1900 EUR
The more expensive version pads from mentor costs: 5600 EUR
Eagle from cadsoft costs: 1200 EUR for...
hyperlynx prices
Yes, I was afraid I did remember those number. When I read the topics on this forum I se a lot of talk about HyperLynx, some I had hoped that it was some cheaper.
Any other program? Is HyperLynx an often used program?
2d bus simulators
Does there exist any free PCB (2D or 3D) for simulating current, voltage and/or electromagnetic?
How much does hyperlynx cost? Can Hyperlynx simulate an PCB boards that are made of Pads? Or does it only simulate pre models?
Yes optimal should the IC been placed where the connection between analog and digital ground is. But there can not be more like one connection like that, else the idea behind using different earth plane is gone. So what if you have more than one IC like the one over.

I routing a PCB board that will look like the picture over. There are just one analog ground, the to analog ground, left and right, are to different setings.
The 8 pins IC over are DAC chip. The pins are as follow:
Pins 1-4: Digital input...
I am going to have an stable voltage reference point, that have a low impendans.
Is there any problem to connect an 10uF cap to ground on the output of an operation amplifer?
On turn on power, can it go a lot of current to the cap, so the operation amplifer gets damaged?
allintitle: flyback regulator
If looking at figur on the page 1 in the following file:

Where you have to voltage outputs. The feedback voltage is only taken from one output. I have read som place that the other output then vil not be vell regulated.
But does any have...
Multiplied DAC
I going to use an DAC like the simple schematic below.
The Vin on Vref is Multiplied/Divided with the digital value inn the DAC.
I have understood that there are to types of DAC; voltage and current. In the datasheet for the current type they are refering to Multiplying DAC...
I am going to design connection for USB on the pc side, thats type A connector. I have an reference design that say that could be an Inductor or RF-drossel in seriers with the power lines. The value is 50@100MHz 3A.
I am a litle uncertain about what that mean about the value.
effekt i resistor
When the producer of an resistor say in can handle one amount of power that develop in an resistor. Is it then talking of RMS values?
Today, in high speed IC, the rising time for the output is often shorter than 1 ns.
This cause ringing on the line. This ringing will cause the voltage to go over the voltage that are sendt out. In the teori the double voltage.
Will this double voltage have the possibility to damage the...
I se the "Minimum Gain" Acl term are used on Differential Amplifiers. Normaly the values are 1, 2 or 10. What does this mean? What happens if I sett the gain less than that value?

Is there anybody that have some links or information around Ethernett transformer magnetics. I have problems to find background information around that.
