If the input is low for a long time for the RC circui to settle, then inverter output is high. So when the actual input goes high, the AND gate goes high, but soon the RC circuit settles and inverter...

This circuit is not switch de-bouncer. This is actually a pulse generator intended to generate a short pulse based on the IRQ_C_CH2's input low to high transition irrespective of how long that...

It's an edge detector. When the input goes high, the output of the AND gate will go high and stay high until C35 charges enough to make the inverter's output go low. The Schmitt trigger is there to...

How does this debounce circuit (from Arduino Portenta Edge Control) works?
I stumbled upon this part of the schematic (page 2) of the Arduino Portenta Edge Control (shown below), which – in my eyes — seems to be a debounce circuit, but more complex than the one shown in this...
