Abstract
The present invention relates to a method of controlling the characteristics of a double relaxation oscillation SQUID having a reference junction. In the method of controlling characteristics of a reference junction-type double relaxation oscillation SQUID (RJ-DROS) having a signal SQUID and a reference junction, a reference DC current flows through the reference junction in order to control the characteristics of the DROS. A modulation width of an averaged relaxation voltage, which reacts to a magnetic flux, may be controlled at the reference junction. An amount (modulation depth) of an averaged relaxation voltage, which reacts to a magnetic flux, may be controlled at the reference junction. An amount of an operation application current may be controlled at the reference junction. Accordingly, the reference current of the reference junction can be changed by causing the current to flow through the reference junction. A magnetic flux-voltage characteristic and a transfer coefficient of the DROS can be easily controlled externally and the DROS can operate stably.
