Abstract

A 160 channel read-out circuit aimed for a large energy-resolved photon-counting X-ray pixel detector has been designed. The high number of channels combined with high speed and noise performance requires very low power consumption and small footprint of the analog channel. We describe the design of the analog channel, aimed for a detector capacitance of 3-5pF and with a target ENC of 300 electrons for worst case temperature of 100C° at 10ns peaking time and a maximum power consumption of 3 mW/channel.
