Performance analysis of general charge sampling

In English This paper focuses on the performance analysis of general charge sampling circuits that have been applied in signal capture. The theoretical analysis applies not only for small signal capture, but also for normal signal sampling. Based on a general charge sampling model, the transferring function, together with noise transference, clock jitter tolerance, and clock feedthrough effects, are analysed and compared to conventional voltage sampling. The results show the advantages and limits of charge sampling in circuit design and applications
