Abstract :
Two different kinds of external photoconductive probes are investigated in detail. Their dual character in application as generators or detectors of picosecond electric transients is demonstrated. The probes are manufactured on transparent silicon-on-sapphire substrates suitable for on-wafer testing of integrated circuits. A detailed analysis of the freely positionable probes is performed in time domain with respect to linearity, sensitivity, time resolution and invasiveness
