• Multiple Supply

    Hello,

     

    I'm drawing some schematics, and I want to use multiple supplies, eg. VCCINT, VCCAUX, VCCIO, VCCDDR, VTTDDR, VREFDDR, ..., in them.

    What is the most simple way to do it?

    (I googled and found some old pages. Thats said "define each supply symbols…

  • Help with First 4 Layer Board?

    I'm planning to design my first 4 layer board. There will be a 7805 regulator to supply 5V to various IC's and then a LM317 to regulate the current to 350mA to power a number of LED's. I'm thinking of making the middle two layers the output from the current…

  • Driving High voltage Anodes with 5 volt logic

    Ok so I have some Nixie Tubes. I need to control the anodes, but I cant use PNP type transistors because I would have 179 or so volts going through the base of the BJT HV transistor. Thats why I chose to use an NPN to control the base of the PNP, as the…
