This work describes the design steps of a Bandgap
Voltage Reference (BGR) with second order curvature compensation to be used in the Space applications. The work focuses on the design of the different sub-circuits which integrate the BGR and the implementation of the trimming sections, to improve the performance in all the special conditions that characterize the target environment. The circuit was designed in a 150 nm Silicon-on-Insulator CMOS technology, using radiation hardening. Simulation results show a performance of 0.758 ppm/°C of temperature coefficient in typical condition over a military temperature range, with a 1.25 V output voltage.
