Compared with traditional waveform digitization with flash-ADCs,waveform digitization with switchedcapacitor arrays (SCAs) is able to achieve the sampling speed above 1 GS/s without degrading the analog to digital conversion precision significantly.In this paper,we present the implementation of a fast waveform digitization system with the use of SCAs,and evaluate its performance of waveform digitization and the waveform timing.At about 5 GS/s,the dynamic input range of the digitizer is about 66 dB,and its timing precision is about 20 ps (RMS).
