The pair-monitor is a beam profile monitor at the interaction point of the international linear collider. A prototype of the readout ASIC for the pair-monitor has been designed and tested. Since the pair-monitor uses the hit distribution of electrons and positrons generated by the beam-crossing to measure the beam profile, the readout ASIC is designed to count the number of hits. In a prototype ASIC, 36 readout cells were implemented by TSMC 0.25μm CMOS process. Each readout cell is equipped with an amplifier, comparator, 8-bit counter and 16 count-registers. By the operation test, all the ASIC component were confirmed to work correctly. As the next step, we develop the prototype ASIC with the silicon on insulator technology. It is produced with OKI 0.2μm FD-SOI CMOS process.
