Abstract-An architectural performance comparison of bandgap voltage reference variants, designed in a 0.18 µm CMOS process, is performed with respect to single event transients. These are commonly induced in microelectronics in the space radiation environment. Heavy ion tests (Silicon, Krypton, Xenon) are used to explore the analog single-event transients and have revealed pulse quenching mechanisms in analogue circuits. The different topologies are compared, in terms of cross-section, pulse duration and pulse amplitude. The measured results, and the explanations behind the findings, reveal important guidelines for designing analog integrated circuits, which are intended for space applications. The paper includes an analysis on how pulse quenching occurs within the indispensable current mirror, which is used in every analog circuit.

Abstract-This paper proposes a design methodology for a digital library of cells resistant to cosmic radiation. Most important effects due to radiation are avoided or mitigated using ad hoc design techniques. Fault injection techniques are used to validate the design. Simulations results demonstrate that the cells designed in a 180 nm CMOS technology are tolerant to 1.5 mA current peak due to interaction with a single high-energy particle.
