Timing optimization and timing resolution for the AARDVARC chips

In this article we describe a series of novel measurements and timing calibrations we performed on the Advanced ASoC Rapid Digitizer, Variable Readout Chip (AARDVARC), a waveform digitizer designed for the readout of signals with very high timing resolution. In the course of the analysis we will demonstrate how a proper timing calibration methodology can provide resolutions below 10ps.
