Análisis de los efectos de la radiación espacial en los sintetizadores de frecuencia

Abstract

Single event transients (SETs) in analog integrated circuits result from the interaction of a heavy ion or high- energy proton with a sensitive p-n junction. SETs induce electron-hole pairs that can lead to current spikes, which propagate through the integrated circuit and can result in substantial transient peaks at the output voltage. This paper proposes techniques to mitigate SETs and SEU in CMOS frequency synthesizers without affecting circuit specifications. RHBD techniques are applied to redesign the blocks of the frequency synthesizer.
