Abstract :
The design of a single shot sampling circuit allowing 20GHz bandwidth random signal and the experimental results of the main circuits are described. Assuming a temporal analysis depth of 5ns, this circuit, based on the principle of non simultaneous spatial sampling and realized in InP HBT MMIC (FT=180GHz) and CPW propagation line, can reach a truly sampling frequency of 40GS/s. Very good performances are expected using such a technology in terms of bandwidth, dynamic range and jitter. Moreover a specific test bench allowing very low jitter measurement is presented
