Abstract

In this paper, we present an ultrafast digitizer utilizing the DRS4 switched capacitor array application-specific integrated circuit to achieve an ultrafast sampling speed of at most 5 GS/s. We cascaded all eight channels (sub-channels) of a single DRS4 chip for increased storage depth. The digitizer contains four DRS4 chips, a quad-channel analog-to-digital converter, a controlling field-programmable gate array, a PXI interface, and an SFP+ connector. Consequently, each DRS4 channel has a depth of 8192 points and a vertical resolution of 14 bits. The readout sequences should be broken into several segments and then reordered to obtain the correct sequential data sets, and this offline procedure varies in different readout modes. This paper describes the design and implementation of the hardware; in particular, the respective processing procedures are described in detail. Furthermore, the offset error is calibrated and corrected to improve the precision of the captured waveform in both single-channel and high-resolution modes.
