Abstract

The latest experimental results of the multichannel CSP ASIC for TRACE detector are shown. The device, submitted to the foundry in the middle of 2014 and received at the end of the same year has been installed on a dedicated pcb and tested using a pulser. The device features four channels specifically designed for hole signals and one channel for electron signals. The power consumption is around 10 mW per channel as required by the specifications of TRACE. The main design goals are low noise and fast rise time. With proper shaping of the signals this device is capable of producing energy spectra with resolution of approximatively 1keV. The rise time of the leading edge of the signals is fast enough to perform pulse-shape analysis of the waveforms. The key feature of this device is the possibility to switch some internal components as desired through an I2C bus. In this way some critical parameters, such as bandwidth and gain of the preamplifier, can be adjusted and optimized according to experimental needs.
