Query: Performance study of SKIROC2/A ASIC for ILD Si-W ECAL   The ILD Si-W ECAL is a sampling calorimeter with tungsten absorber and highly
segmented silicon layers for the International Large Detector (ILD), one of the
two detector concepts for the International Linear Collider. SKIROC2 is an ASIC
for the ILD Si-WECAL. To investigate the issues found in prototype detectors,
we prepared dedicated ASIC evaluation boards with either BGA sockets or
directly soldered SKIROC2. We report a performance study with the evaluation
boards, including signal-to-noise ratio and TDC performance with comparing
SKIROC2 and an updated version, SKIROC2A.
