[sdiy] CMOS Saw to Triangle Waveshaper (corrected URL)

[Scott Gravenhorst]

Heh heh, you guys!

I'm getting there.  I did think about that, but I drew
it with opamps before I thought of it.  In fact, the 
LFO is the only part not yet built.  I know I can make
a sawtooth this way, but tri ... ?  With 3 inverter gates?
Hmm.  The integrator is easy I think.  The schmitt trigger?
2 gates setup as linear inverters connected together makes
a noninverting gain stage, then some positive feedback
in that system?  I'll play around, perhaps today.  I
*am* trying to keep this as much CMOS as possible, so that
would be a good use of those gates.

And then there's the 2 analog switches and the flipflop...
Actually, the flipflip's clock has a shcmitt trigger input.
I wonder if there's a way to use the JK in an LFO somehow.
