Abstract

Abstract: TARGET7, the 7 th -generation TeV Array Readout with GSPS (Gigabit Samples Per Second) sampling and Experimental Trigger ASIC, has been initially designed to monolithically and inexpensively instrument large deployments of semiconductor photon detectors for large neutrino and muon detectors. It is a switched capacitor array (SCA) based transient waveform recorder with 3-dB bandwidth of 500 MHz; a large dynamic range of 1.8 V; high sampling rate (typically 1 GSPS); high channel density (16 channels per ASIC); low power consumption ( 0<1 mW/channel) and deep analog storage buffer (16, 384 samples per channel). Moreover, each channel has an integrated Wilkinson ADC (Analog-to-Digital Convertor) for digitization. In this paper, a test board with the chip is described. Calibration methods, timing performance as well as its application possibility in charge measurement with a comparison to an oscilloscope are studied.
