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.

The paper presents design of analog programmable switched-current matrix, based on second generation differentiators. The matrix is a part of mixed-signal ASIC, capable of FM frequency range signals receiving and decoding as well as complex processing of audio frequency signals [Il.Presented filter solution acts as a programmable matrix working with analog signal amplitudes but with discrete timing.
