    • In the current-pumping scheme, the pummodulates Josephson inductance only quadratically unless the SQUID is biased by a dc. Therefore, in the degenerate-mode operation, the frequencies of the pumand the signal are equal (Ref.).

    • The quality factor is flux dependent. It tends to be smaller as we approach / 0 =0.5. For example, it is 170 for / 0 =0.42.

    • The maximum gain increases as we increase P However, the device becomes unstable if we increase Ptoo much, which prevented us from making the maximum gain much higher than 14 dB.
