✦ Synopsis
A prototype for a new particle detector LSI, called Qpix has been developed. The Qpix can measure total charge and timing information by integrated ADC for each pixel. The prototype LSI was designed and fabricated in 0.18 mm 6-metal 1-poly-Si CMOS process, with a pixel cell of 140 Â 200 mm 2 . Each pixel with a built-in 6b 10MSps SAR ADC can measure arrival time, TOT and total charge, simultaneously. Initial measurements verified all functions of the pixel and show very good agreement with the theory.
