We have proposed a theoretical design method for the lower boundary of supply voltage using the universal Eb/N0-bit error rate (BER) characteristics from the system viewpoint. In order to achieve the system error rate of less than 10-10 with the conditions of 10 years term, 10 GHz clock and 106 gate, the bit error rate of a gate should be less than 10-34. For a BER of 10-34 VDD should be larger than 0.1 V for 0.13 μm complementally metal-oxide-silicon (CMOS) LSI. For 0.05 μm CMOS of next generation, VDD should be larger than 0.2V under the ideal thermal noise environment. The measured E b/N0-BER characteristics of CMOS circuits as a function of supply voltage have agree well with the theoretical value.
