Abstract: DAMPE(DArk Matter Particle Explorer) is a scientific satellite which is mainly aimed at indirectly searching for dark matter in space. One critical sub-detector of the DAMPE payload is the BGO(Bismuth Germanium Oxide) Calorimeter, which contains 1848 PMT(photomultiplier tube) dynodes and 16 FEE(Front-End Electronics) boards. VA160 and VATA160, two 32-channel low power ASICs(Application Specific Integrated Circuits), are adopted as the key components on the FEEs to perform charge measurement for the PMT signals. In order to monitor the parameter drift which may be caused by temperature variation, aging, or other environmental factors, an onboard calibration circuit is designed for the VA160 and VATA160 ASICs. It is mainly composed of a 12-bit DAC(Digital to Analog Converter), an operational amplifier and an analog switch. Test results showed that a dynamic range of 0——30 pC with a precision of 5 fC(Root Meam Square, RMS) was achieved, which covers the VA160's input range. It can be used to compensate for the temperature drift and test the trigger function of the FEEs. The calibration circuit has been implemented for the front-end electronics of the BGO Calorimeter and verified by all the environmental tests for both Qualification Model and Flight Model of DAMPE. The DAMPE satellite will be launched at the end of 2015 and the calibration circuit will operate periodically in space.
