Query: An overdetermined linear equations-based time calibration method for
  fast sampling ASICs   A novel time calibration method for waveform sampling application specific
integrated circuits (ASICs) based on switched capacitor arrays (SCAs) is
proposed in this paper. Precision timing extraction using SCA ASICs has been
proved to be a promising technique in many high energy physics experiments.
However, such ASICs suffer from irregular sampling intervals caused by process
variations. Therefore, careful calibration is required to improve the time
resolution of such systems. We evaluated the limitation of a popular method
using the proportionality between voltage amplitude and sampling interval of
adjacent switched-capacitor cells responding to either a sawtooth wave or a
sine wave. The new time calibration method presented here utilizes the
relationship between sampling intervals and the known input signal period to
establish overdetermined linear equations, and the roots of these equations
correspond to the actual sampling intervals. We applied this new method to a
pulse timing test with an ASIC designed by our team, and the test results
indicate that the new time calibration method is effective.
