Abstract :
A novel family of Josephson logic circuits called magnetically-coupled asymmetric interferometer logic (MAIL) has been designed. The basic MAIL device is an asymmetric two-Josephson junction interferometer. Computer simulations of OR/ AND MAIL circuits using 2.5 ¿m Pb/Pb technology device models indicate a unloaded gate delay of 25 ps and a power dissipation of 5 ¿W/gate. Thus, the power delay product is only 125 atto Joule. Different MAIL logic gates have been experimentally tested and preliminary results are presented.
