- Problems with results of DAC R-2R converter with CD4040B ripple counter
I am trying to make a DAC R-2R ladder with CD4040B counter. Output should be a staircase but it is just a straight line in my simulation. I am probably doing something wrong as I am not that experienced with Spice so I would appreciate any help. I tried it without counter(just attached four clocks on every bit) and it worked just as supposed.
