Description

A front-end application specified integrated circuit (ASIC) is developed with a wide dynamic range to read out the signals from a photo-sensor like a photodiode. The ASIC consists of a charge sensitive preamplifier, four wave-shaping circuits with different amplification factors and an analog to digital converter(ADC) of Wilkinson-type. To realize a wider range, the beed back capacitor of integral circuit in preamplifier can be changed from 4pF to 16pF by two switched. The output of a preamplifier is supplied to the four wave-shaping circuits with four gains of 1,4,16,64 to adapt input range of ADC. The dynamic range of four orders of magnitude is achieved with the maximum range over 10pC. A 0.25m CMOS process (of UMC electronic CO.,LTD ) is used to fabricate an ASIC with four-channels. In this presentation, the design and the basic performance of ASIC will be reported.
