Hello,

I want to switch a 80mA current with an inverter. The transfer characteristic should have smooth slopes so that the input of the inverter is lowpass filtered.
Unfortunally the peaking current gets quite high so that it influences my supply because the time where both switches are open ist quite long due to the filtering.

At the moment I connected both gates togeher and switch it with one source.
I was wondering if it would be possible to put move this node and put some delay (different for pmos and nmos) in between.
Maybe there are other possiblilites I just dont know what I should look for.
Does anyone have me some keywords?

regards Zitty
