| Abstract | A Delay-efficient Radiation-hard Digital Design Approach Using Code Word State Preserving (CWSP) Elements. (May 2008) Charu Nagpal, B.E., University of Delhi Chair of Advisory Committee: Dr. Sunil Khatri With the relentless shrinking of the minimum feature size of VLSI Integrated Circuits (ICs), reduction in operating voltages and increase in operating frequencies, VLSI circuits are becoming more vulnerable to radiation strikes. As a result, this problem is now important not only for space and military electronics but also for consumer ICs. Thus, the design of radiation-hardened circuits has received significant attention in recent times. This thesis addresses the radiation hardening issue for VLSI ICs. In particular, circuit techniques are presented to protect against Single Event Transients (SETs). Radiation hardening has long been an area of research for memories for space and military ICs. In a memory, the stored state can flip as a result of a radiation strike. Such bit reversals in case of memories are known as Single Event Upsets (SEUs). With the feature sizes of VLSI ICs becoming smaller, radiation-induced glitches have become a source of concern in combinational circuits also. In combinational circuits, if a glitch due to a radiation event occurs at the time the circuit outputs are being sampled, it could lead to the propagation of a faulty value. The current or voltage glitches on the nodes of a combinational circuit are known as SETs. When an SET occurring on a node of a logic network is propagated through the gates of the network and is captured by a latch as a logic error, it is transformed to an SEU. The approach presented in this thesis makes use of Code Word State Preserving |
