if the concept is clear with you, then you must be able to implement it in cadence.
what are the places in this project do you think you will face problems with cadence?
The information in wikipedia says that the time stretch processor is generally optical. I am not quite sure how the streching is done. It uses a dispersion compensation fiber etc etc. didnot understand to be frank. but the result is to produce a chriped pulse. i wonder whether this can be achieved by simulation. and also the intensity modulator. any material on these would be appreciated.
