GaAs ASIC design case study

Abstract

A design experience with GaAs ASICs (application-specific integrated circuits) is presented from the user's point of view. Vendor selection criteria, design experience, board considerations, and testings are discussed in detail. It is shown that through the application of GaAs ASICs a much greater understanding of what is required to implement them into a system has been achieved. Generally, these requirements do not differ greatly from those of other technologies, but there are some important differences to consider. It is concluded that the greater speed, temperature range, and radiation tolerance of GaAs, combined with the functionality and space-saving of ASICs, justify the additional design time.<>
