Abstract

A compact 2 Transistor (2T) radiation sensor with a tunable measurement sensitivity was implemented in a 65nm LP bulk process. Alpha radiation tests show a 117X higher cross-section area per cell for the proposed sensor as compared to a 6T SRAM test structure. The critical Linear Energy Transfer (LET)of the proposed 2T sensor was estimated to be 3.4x-4.2x lowerthan that of an inverter cell or SRAM cell for supply voltages 0.75V to 1.5V. The proposed sensor can facilitate the development of radiation models and hardening techniques by enabling a statistically significant number of events from a small silicon area using inexpensive radiation sources.
