Abstract
In an interface circuit transferring a data signal from a semiconductor element circuit to a Josephson junction element circuit, a first unit detects a change switching of a first clock signal supplied from the semiconductor element circuit, and generates a second clock signal in response to the change of a first clock signal. A second unit performs an AND operation on the data signal and the second clock signal, and outputs the result of the AND operation to the Josephson junction element circuit as a second data signal.
Claims23
An interface circuit transferring a data signal from a semiconductor element circuit to a Josephson junction element circuit, said interface circuit comprising:
- first means for detecting a change of a first clock signal supplied from the semiconductor element circuit and for generating a second clock signal in response to said change of a first clock signal;
- second means, coupled to said first means, for performing an AND operation on the data signal and the second clock signal and for outputting a result of the AND operation to the Josephson junction element circuit as a second data signal;
- and
- timing adjustment means, coupled to said first means, for adjusting a timing at which the first clock signal is applied to said first means.
