how to delay a signal by about 200ps. the bandwidth of the signal is about 1Ghz

thanks
 

Use 4 cm of coax cable or a PCB transmission line.
 

is that possible to realize it on chip? thanks
 

I would say that your approach depends on whether "about"
means constant but roughly-right, or allowed to vary over
environmentals and processing.

The former wants time-of-flight in an invariant medium.
That, or some mighty fancy compensation.

You should also distinguish between 1GHz bandwidth (as in,
useful information everywhere from100MHz to 1.1GHz)
and 1GHz frequency-of-interest. A simple lag network
with low-tempco components might do for the latter but would
act as a filter, changing relative amplitude@freq, and mess
up a "richer" spectrum.
