[sdiy] Triangulation rant!

[karl dalen]

Im looking for a very well defined triangulation method, in saw to triangle
converters the diodes cuses a glitch (even if the diode is made out of a
trannie) 
wich usually is compensated by a cap, is there any other methods that temp
variation and amplitude variations and glitch could be kept to an absolute
minimum?
Even if i have to go as far as keeping the triangulation cirquit in a oven!

My problem is that i need several separate suboctave triangles, there is
several
approaches for this however im looking for near or close to absolute amplitude
uniformity from  60Hz to 14KHz wich might look trivial but in a deeper look at
it it's
not! The symnetry however does not have to be perfect slight leaning is Ok as
long 
i dont get any glitches or under/over shot's!

Im starting to incline/batter towards an precision saw osc and creating 
suboctave saws and switch them periodically with the aid of a phase 
positionable PW  to generate the triangels and to overcome the glitch
in the switch for overlapping and cancelling sawtoth's.
Or by using clamping op amps wich is quite expencive but would 
give top notch performance (wich i dont need, geee)!

What op amps can withstand input clamping without phase reverse?
ie, lets asume a input voltage of +/-10V and a supply of GND and +15V
the opamp is supposed to clap the negative portion of the inputssignal!

Any ideas folks?
