High total dose response of the UTMC gate array fabricated at Lockheed Martin Federal Systems

摘要

The radiation response of the UTMC Microelectronic Systems (UTMC) FA01 gate array standard evaluation circuit (SEC) was measured up to a total ionizing dose of 10 Mrad(Si) using a Co-60 source. Each SEC consists of 9 functional blocks, all of which remained fully functional throughout the accumulation of total dose. In addition to functional testing, the SEC was monitored for parameter shifts in quiescent current (Q/sub IDD/), propagation delays, input buffer data transition voltage, and output buffer drive voltage. All parameters were within specified values during the tests.
