Aiming at ultra narrow pulse signal of nano-second level outputted by sensor
a TIADC ultra high speed acquisition system of 8 × 500 MSPS is proposed
pulsed power distribution module and multi-phase clock module are studied. Simulation experiment shows that power distribution module has good channel consistency and low insertion loss. The jitter in multi-phase clock module is below 200 fs
and it has good channel expandability. The system can achieve SNR of 67 dB at 4 GSPS sampling rate.
