ABSTRACT:
An electronic circuit for providing a logic gate function includes a differential signal input, a combining stage, a discriminating stage and a differential signal output. The discriminating stage includes four transistors each having first electrodes and second electrodes and a respective gate electrode. The first electrodes of the four transistors are connected to a common node. The combining stage is arranged to convert differential input signals into gate signals applied to the gate electrodes of some of the four transistors respectively.
