simple 1khz oscillator
Hi JPdP,
I have never used spice (I really am behind with the whole 'software' thing) but those aren't the only chips you can use. There are many 'schmitt trigger' devices, some inverters, some nands. And I find it hard to believe any electronics simulation software is without some generic 'logic gates'.
Use google, or, if you're really stuck, you could 'build' a logic gate with discrete parts. Like MOSFETS, diodes, resistors etc... I'm sure google will have some examples.
Of course, you don't always have to simulate your designs, I'm sure the above circuit will work straight away, it did for me.
