This paper characterizes the immunity of I/Os under different supply voltages for fault-tolerant circuit designs against
electromagnetic interference. The direct power injection approach is used as a means to characterize the immunity of
circuits. In this work, the immunity characterization has been performed under two scenarios: (1) an input buffer of
a Field Programmable Gate Array (FPGA) followed by a single flip-flop, and (2) the FPGA input buffer followed by a
redundancy-based fault-tolerant circuit. The experimental results show that when downscaling the supply voltage
through a set of nominal values (i.e., 3.3, 2.5, 1.8, 1.5, 1.2 V), the immunity of I/Os is decreased from the
highest level at 3.3 V to the lowest at 1.2 V. Particularly, the maximum difference in the immunity is about
16.8 dB at the frequency of 600 MHz. Moreover, experiments demonstrate that I/O buffers followed by the
redundancy-based fault-tolerant circuit can improve the immunity of the circuit up to 4 dB below the
frequency band of 400 MHz. Thus, the redundancy-based fault-tolerant circuit can support I/Os to
operate reliably in the harsh environment. |
