Bit error rate in low-voltage RSFQ circuits with small critical currents/lowered bias voltages


We report experimental results of bit-error-rate (BER) measurements in small-critical-current or lowered-biasvoltage rapid single-flux-quantum (RSFQ) circuits for power reduction. In such reduced-power RSFQ circuits, the BERs can be increased because of the reduced signal-to-noise ratio. We fabricated 2-bit shift registers using a 2.5-kA/cm<sup>2</sup… (More)
