High-speed current-mode threshold gate with clamps and current comparison

A circuit for a haigh-speed threshold gate with low power dissipation is given. Compared with known circuits, it has many advantages, e.g. minimal power-supply voltage is not dependent on logic parameters of the threshold gate such as the number of inputs and their wieghts. Propagation delay time remains low compared with these circuits, as is shown by simulation using a simple model and by measurements on a physical gate.
