We are trying to make 700MHz sine output from 700MHz CMOS output.We want make this in small package.Is it possible to convert 700MHz ( High Freq) signal in to sine by using simple LPF?Is there any method to convert this in to pure sine?
Umm... just about any bond wire at all ought to get you pretty
close, at that frequency. Hell, I've seen 80MHz 5mA outputs
not reach the flat-top with 10-15pF load. But there is no such
thing as pure - perhaps you ought to set a finite goal and
then you can begin to analyze your compliance to it.
Yes, most bondings are equal to ~150nH...
I thank the (seriel)filter on chip_of course, otherside I beliefe, that filtering at 700MHz is not so a big problem with clear layouting.
