A Family of Analog and Mixed Signal VLSI ASICs for NASA Science Missions

摘要

This paper presents several analog and mixed signal VLSI chips that have been successfully developed over the past several years at JHU/APL for space science missions. The chips have applications on spacecraft avionics and several types of instrumentation. The family of the chips include: the TRIO Smart Sensor multiplexed ADC chip for spacecraft/instrument avionics, the Time of Flight chip for precise time interval measurement, the Energy Chip for low noise particle/photon measurement, a Commandable Discriminator Pulse High Analyzer, Event Accumulator, a radiation hardened voltage reference, an ADC and other. The talk will address some design, radiation hard by design, design for testability, testing, and space qualification issues. The talk will also briefly describe the spacecraft and instrument applications of these chips including: the Cassini mission, Image, Contour, Messenger, Stereo, Pluto, Europa.
