Oscillator 2 phases

without having differential oscillators; if have available a ring oscillator single-ended and need 2 phases (180deg between them), is it feasible and correct to connect an inverter to obtain these two signals ?
 

Re: Oscillator 2 phases

You will get almost 180 degrees phase difference. The error is from the delay time through the inverter. You can use specialized circuits, like a comparator with dual Q and Qnot outputs to get less phase error.

Re: Oscillator 2 phases

thanks, you have an example or reference of comparator with dual-Q ?

The LM361 comes to mind. You can search the selector tabulated data at most IC company web sites. Dual ouptut is the feature to look for.

Re: Oscillator 2 phases

is there some CMOS topology to simulate ?
