I'm currenlty making a relaxation oscillator the produces a triangular wave. It is based on a charge pump technique, i.e. the upper current source charges the o/p capacitor (instead of the filter which is usually placed at the o/p of a CP in PLLs) then, after some time, the lower current source is activated while the upper one is deactivated to make the cap discharge.
The two Current Sources are mirrored so that they have the same current value.
I'm having problems in the design, like accumulated DC in the o/p wave plus low o/p peek to peek voltage.
Can you please supply me with practical IC relaxation designs and design considerations , or any paper about ???
Please, i'm in real need to it now
