when i connect the o/p of the relaxation oscillator (which has a capacitor at its o/p) to a schmitt trigger (which makes the amplitude control of the o/p triangular wave), the wave decays.

i think i'm having a very bad loading effect.

How can i solve this?

I've tried using a source follower with large source resistance (as a buffer), but it didn't work either and the o/p was not triangular at all...

i need some serious help here :cry: :cry:
