This paper presents our work on a 8-channel low noise Front-End electronic coupled to a Liquid Argon (LAr) TPC (Time Projection Chamber). Each channel consists of a Charge Sensitive Amplifier (CSA), a band pass filter and a 50 Ohms buffer as line driver. A serial link based on a `i2c-like' protocol, provides multiple configuration features to the circuit by accessing slow control registers. Only the...
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...
