More Information
Summary:The ASIC is widely used in the field of high energy physics. Astroparticle experiments benefit from high integration, smallsize and low power consumption. In this paper an analog chip named ARCHGARD （Analog Readout Chip for High energyGamma Ray Detector） for high energy physics experiment is introduced. ARCHGARD is a readout chip, in chartered 0.35 mSiGe technology, for photomultipliers （PMT） array readout. The chip is designed for the Large High Altitude Air Shower Ob-servatory （LHAASO） project. The ASIC integrates 16 independent and auto-triggered channels with variable gain and variableshaping time. It provides analog output for charge measurement, which is performed from 1 up to 3000 photo-electrons （p.e.）.The integral nonlinearity of the whole input range is less than 1% and the equivalent input noise is less than 1/10 p.e. Eachchannel has a trigger output for time measurement.
