在EUDET的合作下，正在开发一种基于单片有源像素传感器(MAP)的高分辨率光束望远镜。Mimosa26是第一个覆盖∼224 mm 2有效区域的像素传感器，具有集成的零点抑制功能。预计单点分辨率优于4μm，像素间距为18.4μm。矩阵由576行和1,152列组成。在像素阵列的底部，每列连接到偏移补偿鉴别器，以执行模数转换。然后，数字数据被零抑制电路处理，以便发送有用的信息。该结构可实现10kFrame/S的快速读出频率。本文重点介绍了该芯片的设计细节及其主要性能。
A high resolution beam telescope, based on CMOS monolithic active pixel sensors (MAPS), is being developed within the EUDET collaboration. Mimosa26 is the first pixel sensor covering an active area of ∼224mm2with integrated zero suppression for this telescope. A single point resolution better than 4μm is expected with a pixel pitch of 18.4μm. The matrix is organised in 576 rows and 1152 columns. At the bottom of the pixel array, each column is connected to an offset compensated discriminator to perform the analogue to digital conversion. Digital data are then treated by a zero suppression circuit in order to send useful information. This architecture allows a fast readout frequency of ∼10kframes/s. The paper concentrates on the details of the chip design and its main performances.
