simple LFO question

[Paul Perry]

If you want a hypersine, i guess you could use a 
variation of the common fuzz ckt with the back to 
back parallel diodes in the feedback..
if you had a straight resistor for feedback but 
the diode pair as input, then you would get a 
waveform that went exponential.
For the curren application, you would have to 
watch out to get the input bias right 9you only
want one side to be pointy).
I'm not saying a ckt like this wd be mathematically 
perfect, but for the application in question, it could be 
just the ticket.
