Abstract
Parametric gain has been demonstrated at 30 MHz using the nonlinear inductance of Josephson point-contact devices. SQUID-type configurations were used to achieve degenerate-mode negative-resistance amplification with self-pumping achieved via the internal Josephson oscillations. Gain as large as 11 dB was measured. The small-signal analysis predicts parametric amplification and delineates the importance of the critical current, circuit loss, and circuit coupling efficiency.
