CMOS sensors for the vertex detector of the future international linear collider

Abstract : Fast Monolithic Active Pixel Sensors (MAPS) are now being studied for the high-spatial resolution and high readout speed vertex detector which will be required for the future International Linear Collider (ILC). A 32×128 pixels prototype chip has been developed on the 0.25 μm CMOS TSMC digital process. Combined with in-pixel amplification, in-pixel correlated double sampling (CDS) operation is realized. An auto-zero discriminator is implemented at the end of each column. The power consumption of each column is about 430 μW (pixel+discriminator). The chip is optimized to operate with a readout speed of 20 μs/frame. Beam tests with high energy electrons show that detection efficiency is around 98%
