Design and First Measurement Results for the Revision 4 of AARDVARC Waveform Sampling System On Chip

In this article we describe the design and initial measurement results of revision 4 "rev4" of the Advanced ASoC Rapid Digitizer, Variable Readout Chip (AARDVARC). AARDVARC is a 8-channel waveform digitizing and processing Application Specific Integrated Circuit (ASIC) front-end. We will report on the diverse improvements from the previous design and detail the performance in comparison to the previous revision.
