Abstract:
The Picosecond Imaging Circuit Analysis (PICA) technique using the Superconducting Single-Photon Detector (SSPD) allows the detailed characterization of pulse width variations along the delay chain of a high speed Self Timing Interface (STI). Pulses gradually shrink and finally disappear along the delay chain.
