need help with the sine to square wave converter at 10 GHz

[malden]

I need a sine to square wave converter, the technology is 180nm cmos 1p6m, since the delay of an inverter is longer than 100ps, a simple inverter or any similar type can not work. The central frequency is 10GHz, conventional comparator can not work also, so any idea of realizing this?

If 10GHz signal amplitude is more than 100mV. your can convert this sinusoidal signal to squarewave by using Cherry-Hooper amplifier configuration.For more information search google.
I believe you can design a Cherry-Hooper amplifier with this process.

The easiest solution is to use a low-pass filter to cut harmonics.

I am sorry to misread the definition of the problem. To get a sine to square-wave conversion a 10 GHz, I used Hittite HMS 647 fast comparator working up to 12 GHz, maybe you can try it or check Hittite component selection.
Generating harmonics (up to 5th) will be quite difficult as the output of your device through other devices to a load must be flat up to 50 GHz or more.

Thanks for the suggestion! I searched on google, it seems most of the successful Cherry-Hooper Amplifier design over or around 10GHz are made of either bicmos, AsGe and some other material or with shorter channel length, not with the conventional III-V materials using 180nm technology.

Thanks, HIttite do have some components that meet my design requirement. But currently, I hope to have some design that can be on chip, like using the 180nm technology, any suggestions?
