Abstract:
An integrated XOR/SUMMER/MUX device comprising:a reference voltage node; an output voltage node; a first XOR arrangement comprising a first collector node corresponding to said reference voltage node, a second collector node corresponding to said output voltage node, and a first common emitter node; a second XOR arrangement comprising a third collector node corresponding to said reference voltage node, a fourth collector node corresponding to said output voltage node, and a second common emitter node; a differential transistor pair comprising one transistor having a collector connected to said reference voltage node, another transistor having a collector connected to said output voltage node, and a third common emitter node; and a MUX arrangement comprising a fifth collector node corresponding to said first common emitter node, a sixth collector node corresponding to said second common emitter node, and a seventh collector node corresponding to said third common emitter node.
