In this study, the operation speed of monostable-bistable transition logic elements (MOBILEs) is analyzed based on an equivalent circuit model. First, the intrinsic operation speed is examined independent of the subsequent stages. The results show that high-speed operation close to the intrinsic response time of resonant tunneling diodes is possible under the appropriate conditions. It is also shown that the most important factor limiting the operation speed is the angle of the crossing at the unstable point in the load-line diagram, which dominates the potential curve. Next, the effects of the input capacitance of the subsequent stages are examined to clarify the operating frequency under practical conditions. The importance of reducing the input capacitance is shown for high-speed operation.
