I'm designing some electrical circuit schematic with CircuitTikZ, and I must insert the symbol of a Schmitt trigger. But CircuitTikZ doesn't offer such a component.
How can I create such a new component, so that it behaves like every other component in CircuitTikZ ? What would be the best way to do this ?
(It would be nice if it behaves like an op amp - it also has input, output, and up/downs - and that one can change the (non-)inverting characteristic.)
Thanks in advance !
