Okay let's not talk about -6V now...
The Picture in post #25 is for -3.6V. I need similar structure which works as listed before (pulse=0V then output 0V and when it is 1.8V then -3.6V)...
Even when it is 1.8V then -3.3V is acceptable...but at input 0V it should be 0V bottom (output)
You can use the configuration of my post #38. Just replace the Vcp voltage source by a 3.6V source.
Every circuit has it's own complementary circuit. If post #25 is possible then it's complementary is also possible..right..?
Of course it's possible, but I think this won't solve your problem. Just try it!
