PA-PRO-2014-010

ToPiX v4 is the prototype for the readout of the
silicon pixel sensors for the Micro Vertex Detector of the
PANDA experiment. ToPiX provides position, time and energy
measurement of the incoming particles and is designed for
the triggerless environment foreseen in PANDA. The prototype
includes 640 pixels with a size of 100 um x 100 um,
a 160 MHz time stamp distribution circuit to measure both
particle arrival time and released energy (via ToT technique)
and the full control logic. The ASIC is designed in a 0.13 um
CMOS technology with SEU protection techniques for the
digital parts.
