Now it all seems to work OK except the display seems to fluctuate too much with a steady input. Can anyone identify the mystery component? And what is it and what does it do? It is quite difficult infer some conclusion based solely on the pcb layout design. This view do not allow us to see the whole circuit. In suc
I have been working on a project for a customer the last year or so. I am doing the embedded code and system design. There was another engineer doing the schematic design and pcb layout. The other engineer has been too busy with their day job to get things done so I am looking for somebody else to help with this project. (...)

Then clearly start at ADS circuit simulation level (model based simulation of layout pieces with MLIN etc.) and build things step by step.
Hi, I would like to join the analog and digital grounds at only one place in the pcb using a 0E resistor in order to reduce the noise level in the design. But i stuck up with the SMPS Negative connection with the circuit. I don't know whether i need to connect the SMPS(0V) with analog section or digital section. I give the (...)
Hi, I would like to put a thyristor with (Ipp=500A 2/10 us) for longitudinal protection( Telcordia G1089-CORE standard) in E1 circuit. I want to know the number of vias in pcb layout design required to be put for the thyristor pad connecting to the ground for this high current. Is one via enough or multiple vias (...)
It seems that you are dealing with a set of conditions that do not help much, the worst being the fact that has already designed the pcb board, and this would be an impediment to any substantial changes in the circuit. Again, not sure if this violates some safety issue, but in this case, I believe you could consider doing some kind of (...)
Where is the best place to post for a pcb designer to layout a simple pcb for an LED IR Illuminator? I have the circuit design but I don't know how to use, and don't have the time right now to figure out how to use, pcb design software. I imagine the (...)
You can draw circuits with any of a whole bunch of tools. Your choice probably depends on where you want to go from there. If you want to do circuit design and optimization with a SPICE simulator, LTSpice can't be beat (especially for the price of free). But you'll have to change horses, to go to pcb (...)
Hello everybody, Is there any possibilty to generate layout from output or fabrication output files in Altium? I had created a schematic and pcb layout of my circuit. After misunderstanding the requirements again I have changed my design. I still got output files from previous design. (...)
Hello everybody, I am simulating a rectifier circuit using discret components in ADS 2009. I would like to know if it's possible to design the pcb layout of the rectifier with ADS (or the layout in ads is only for microstrip simulation). If it's possible, would you please give me the different steps to (...)

First I would suggest you put the circuit on a uniform pcb. Try : Cheap and quick. Do the layout in Momentum. Get the right er for the pcb for the simulation. Remember that when you put rigid coax cables as Stubs you will have to play around with them because you can not simulate their effects in ADS, and using HFSS
I'm circuit designer and know well about pcb design concepts but the actual pcb routing was done by others. Now I want to create pcb my self (no fabrication just layout till get the Gerber file). many tolls are there OrCad, PADS, Protel ...etc. I need your advice what is the (...)
When the board works in GSM mode, we can hear the buzz noise of the board. But in other mode, there is no buzz. The most important noise is 5th harmonics of 217Hz (that is generated by GSM system). How to solve that or decrease the noise? Conditions: 1. There is one buck circuit, so maybe caused by the buck inductor. If so, how to detect it and

What are DFT (design for test) circuits. Are these circuits assembled inside every IC. How does it test functioning of main IC in which it has been connected. Does it check functioning of IC everytime or once ?
On a second thought, 8-) there? s a need to use a fusible unit in the primary circuit and maybe it?s better to rotate the LM7905 integrated circuit as this may require some small heat sinks.
My Dear Sir, Money can not buy Help in edaboard! I hink members will love to help you without money. But there is no schematic, no circuit. Only pictures of a game controller!
when your circuit getting more complicated, the schematic will help alot. you will rely on the scematics for connections, short circuits etc. when transfer to pcb, we usually depends on the schematic nets assign wil the software, so we can concentrate more on the pcb layout and forget about the short (...)
a) using the antenna which comes with the transceiver at the moment b) nope, not using any shielded for both the modulator and demodulator c) i don't quite understand this I would also like to ask what is the max normal current input into the transceiver? as i have set the max current limit for the power supply at
I have tried to built an amplifier with a AT-55143 transistor at 3GHz. I performed all the stability analysis and design the circuit accordingly with DC blocks and DC feedlines. The layout was fabricated and after measurements I found that it was oscillating at 8 GHz. But infact during the stability test I found that it was unconditionally (...)

I am not familiar with how to calculate the width of wires in a RF IC circuit layout (433MHz operation frequency). I know it's gonna be different from regular mixed signal design due to more consideration on parasitic stuff. However I don't know what to consider as far as the wire sizing is concerned. Any formula for wire sizing (...)

Hello, I'm hoping someone can suggest a better layout for the following circuit. My biggest problems are the two comparitors - I'm having trouble laying them out in a way that the lines don't become horribly mixed
For an FPGA design back annotation is taking the delays (some time the pin numbers, too) from the layout (after place&route phase) and entering them into the description (schematic or HDL-based), this way allowing to do more realistic simulation. For discrete components design back annotation is just updating the circuit (...)
