A Family of Rad-Hard ADC with Flash Architecture

This work presents a family of rad-hard ADCs with flash architecture for space applications. The converters, featuring from 4 to 8-Bit at 10MS/s, have been developed using rad-hardening techniques at architecture, circuit and layout levels. The 4-Bit ADC has been integrated in two standard CMOS 0.18-μm technologies by TowerJazz and XFAB. The prototypes have been tested under Co-60 and showed same radiation immunities up to 300krad(Si), demonstrating the effectiveness of the proposed radiation-hardening methodology.
