Abstract :
This brief focuses on the performance analysis of general charge-sampling circuits for signal capture. The theoretical analysis in the brief can be applied not only for weak signal capture, but also for the normal signal sampling. Based on a general charge-sampling model, the transfer function, the noise performance, and the clock jitter tolerance are analyzed and compared to conventional voltage sampling. The results provide a theoretical basis for charge-sampling circuit design.
