Design of custom ASIC for front-end electronics in a 130 nm CMOS process

Abstract

Researchers at Birkeland center of space science at the University of Bergen is developing an instrument to be attached to a satellite, to measure energetic particles in the atmosphere and particle precipitation. This instrument will consist of a radiation sensor developed by SINTEF and custom electronics developed at the University of Bergen. This thesis covers the development and simulations of aforementioned elec- tronics. The process of designing and developing a charge sensitive amplifier, a shaping amplifier and bias current supply circuit. A functional amplifier was designed and implemented and its functionality is proven with simulation results. Some work remains to make the amplifier, fully functional according to the requirements of the instrument
