MULTIINPUT LOGICAL GATE

摘要

A multiinput logical gate has a first resistor, and a second resistor one end of which is connected to a power source each, a current source, m pieces of transistors (m is an integer of 2 or more) the sources of which are parallel-connected to the current source, and the drain of which to the other ends of the first resistors, and m pieces of transistors the sources and drains of which are series-connected between the current source and the other ends of the second resistors. M pairs of differential input signals are inputted to the gates of the parallel-connected transistors and the gates of the series-connected transistors, respectively, and are outputted from the other ends of the first and second resistors as differential signals, respectively.
