Wj. Perold et al., COMPLEMENTARY OUTPUT SWITCHING LOGIC - A NEW SUPERCONDUCTING VOLTAGE-STATE LOGIC FAMILY, IEEE transactions on applied superconductivity, 6(3), 1996, pp. 125-131
A new superconducting logic family, complementary output switching log
ic (COSL), is proposed, The family consists of AND, NAND, OR, NOR, and
XOR gates, The performance of the gates is predicted with a procedure
that evaluates the dynamic performance when all circuit parameters ar
e randomly varied around the nominal values. The simulated performance
of the gates is compared with modified variable threshold logic (MVTL
) at 5 GHz and 10 GHz, The functionality and margins of the COSL gates
are verified by measurements at low speed.
