Design and Measured Results for Born-on-date Timers
Research Report Highlight
An array of timers has been used to provide born-on-date authentication. After timer initialization, readout voltages of the array of timers has been explored as a function of fabrication process variations and evaluated for authentication.
In this deliverable report, we present a design of an array of timers that could be used for born-on-date authentication. The array can be configured and initialized using on-chip charge-pumps and the output of each element of the timer array could be selected and read-out. We present measurement results from a prototype timer array that were fabricated on 0.5um process. The objective is to: (a) verify the functionality of the timer array; (b) explore the statistical behavior of the timer resulted from variations and mismatch of process and (c) extract more robust result by from statistical results.
