Abstract
Superconducting single flux quantum circuits are disclosed herein, each having at least one Josephson junction which will flip when the current through it exceeds a critical current. Bias current for the Josephson junction is provided by a biasing transformer instead of a resistor. The lack of any bias resistors ensures that unwanted power dissipation is eliminated.
Claims13
A superconducting single flux quantum circuit, comprising:
- a Josephson junction configured to flip and generate an output pulse when the current through the Josephson junction exceeds a critical value;
- a flux-powered biasing arrangement that provides a bias current to the Josephson junction;
- and
- an input for supplying an input pulse to the Josephson Junction, wherein the input pulse and the bias current cause the current through the Josephson junction to exceed its critical value.
