Hi Guys,
I'm currently designing a testbed for a memory controller. The signals that will be tested are DDR3 signals, so the speed and signal integrity must be considered in choosing the test points and routing the PCB. I chose to put MICTOR as my testpoints so that I can monitor the 34 signals...
DC/DC Conveter
There are modules that you can use for this simple DC voltage conversion... Try to search for different DC/DC IC regulator manufacturers because they might give the module to you for free for you to evaluate their IC regulator if you are a potential bulk buyer... I'm actually...
Re: Tantalum Capacitors
thanks IanP...
The article you provided clearly explained to me the possible reasons why I got my tantalum capacitors burn...

Bypass Capacitors
Hello,
What are the reasons why do I need to put bypass capacitors in every pin of my Digital IC... Is it really a need or is it just an overkill?
thanks for your feedback...

EMC Standard
Hi,
Is there anyone who is knowledgeable on how to be compliant on EMC? I am now assigned for the Standardization of our product and we are now doing a test on one of the NRTLs in the US... Just want to have a deep understanding about diffferent EMC standards, can anyone give me a...
Power Management circuit
Thanks for your inputs guys....
Btw, I am not that convinced that the internal resistance that I measured is the OFF-resistance of the MOSFET because if the MOSFET is in its OFF state the output voltage that I will measure is zero...
Re: Power Management circuit
Why is it that I didnt measure the resistance of the pass transistor if it is in parallel with the bleeder resistor?
How if I did not use a regulator IC instead I only use a discrete linear regulator using a comparator OP Amp and a PMOS to convert 5V to 3.3V? Will...
Power Management circuit
hi,
i am currently reviewing the design of our company's power management circuit; for your background in our design - our power management is composed of different blocks for 5V to 3.3V then 3.3V to 2.25V then 2.25 to 1.8V these blocks are used to supply the different...
New Tech in PCB Design
Hello,
I heard that there is a new technology in designing a PCB and that is called the DiPOL interconnect which means Digital Point Of Load Interconnect... I have read an article about this but it only stated that this is used to reduce the power loss in a high speed...
difference b/w polar and nonpolar capacitor
naveed85 - yes of course the capacitors are used for filtering purposes especially in power supplies, thats why we have a filter stage after the rectifier stage when designing a power supply - but that was very basic and assumed that everyone here...
why capacitor blocks dc
the primary function of these capacitors are to prevent the fluctuations to reach the IC regulator, it is actually used as a protection to the IC and commonly with reverse diode across the ICs terminals...
