Self-latching operation of MOBILE circuits using series-connection of RTDs and transistors

One of the most attractive features of MOBILE-based circuits is their self-latching operation, which allows pipelining at the gate level, and thus very high through-output, without any area overhead associated to the addition of the latches. However, the self-latching behavior is not inherent to the practical circuit topologies employed to implement MOBILE circuits. This paper reports on very simple MOBILE structures supporting this statement. The analysis performed is useful in extracting design guidelines to guarantee the required behavior.
