    i'm looking into a flipflop that has a well defined state during
    startup. can someone please tell me how to make a flip flop that
    allways starts in 0-state (or 1-state) with basical ports such as and,
    nand, nor, ...
    thanks in advance
  2. Reset (or set) it on power on. Depending on the power characteristics
    and allowable glitches, the circuit may be a simple RC network or
    something more complicated.

    You just need a flip-flop with a "clear" line.

    this has been a great help, but it seems like i wont be able to go
    around the use of a capacitor which is where i am searching for.
    thank you very much!
