Welcome to our site! EDAboard.com is an international Electronics Discussion Forum focused on EDA software, circuits, schematics, books, theory, papers, asic, pld, 8051, DSP, Network, RF, Analog Design, PCB, Service Manuals... and a whole lot more! To participate you need to register. Registration is free. Click here to register now.
The technical info you're looking for is not available.
The schematics is a "know-how", a secret.
But If you have a Power Supply itself, just disassemble it & try to understand how it is built.
Sometimes it can help.
smd parts
Thanks, but the link contains very few codes & neither no code of the parts listed.
:?:If anybody can tell the parts in the 1st post, pls, reply.
Regards...
smd codes
Where can I find code marking guide for SMD descrete components (transistors & diodes)?
What is the type of these transistors (SOT23 package):
W1P (n-p-n),
W2F (p-n-p)
12W (mosfet),
W2T (zener diode)?

So You need to build a DC/DC postregulator, non-isolated from the primary, buck-type. Suggest You'd use any current-mode SMPS IC. UC3842...UC3845 is a good choise to start You design with. Another good variant is UC3823...UC3825 family.:|
There are also some specialised ICs...
The typical ADc sample ratios are seldom higher then 1 megaSPS.
What are the highest speeds available by now for the ADCs on-board (DSP & mPCs from different manufactures)? What type of data conversion these devices utilise?
How those high speeds of data-sampling - up to 1-2 GigaSPS are...

What about some practical DSP implementations?
If you are interested in, there are two good books bu Rulph Chassaign uploaded to the forum ("DSP Applications Using C and the TMS320C6x DSK"). They cover modern TI DSP implementations. Just search the upload section of the forum &...
I suggest You'd use some ready-made DC/DC converter module, for instanse, Aimtec or Franmar or some other (18...36)-12V output module.
It isn't an easy task to design your own power supply from scratch that would sutisfy all the specifications.
The problem you'd have to solve is how to get 48V...
The current feedback is really faster, but it also brings a kind of inherent unstability into the loop over the line voltage change.
May be this is the reason, but not for sure exactly the one.
Re: 1nA Calibration
The task is unreal. The best resolution you can obtain from a precise current source is in the order of 10e-5...10e-6 per temperature & time.
You should get some precise resistors with ultra low temperature drift as well.
There are no such at 1 Mohm known.
