Duty cycle control for VCO

[taofeng]

Hi,
I have designed a VCO based on integrator and schmitt trigger. I am wonderring how to tune the duty cycle of the clock signal with fixed period ?

regards,

Jeffrey

I think you can use a self-biased inverter to get about 50% duty cycle rather than Schmitt trigger.

Schmitt tigger can't get a 50% duty cycle.
