Abstract

Advanced electronics systems require a wide variety of high-performance analog, mixed signal, and clock distribution microcircuits which aren’t readily available as space-qualified components. In this work, we present proton irradiation data for three such Commercial-Off-The-Shelf (COTS) components: (A) a fanout buffer, (B) a wideband, variable-gain amplifier, and (C) a high-voltage operational amplifier. Test results suggest all three of these components are suitable for some space applications. For additional assurance, we recommend additional testing for ELDRS and Single Event Latchup based on underlying design and process technologies of these devices, in particular the amplifiers.
