Characterization of the MPA prototype, a 65 nm pixel readout ASIC with on-chip quick transverse momentum discrimination capabilities.

The first prototype of the full-size, full-functionality Macro Pixel ASIC has been produced in a 65 nm technology employing radiation tolerant techniques. It is a pixel readout ASIC designed for the Phase2 upgrade of the CMS Outer Tracker detector. It features novel on-chip particle discrimination capabilities allowing for real-time event-driven readout of high transverse momentum particles at a 40 MHz rate. This data flow is complemented with a zero suppressed triggered readout data path for the readout of full events at a maximum rate of 1 MHz. This contribution presents the functional and performance evaluation results obtained from silicon prototypes.
