摘要:
Eine Übertragungsvorrichtung für zwei elektrische Impuls-Messsignale umfasst einen ersten Messsignaleingang, einen zweiten Messsignaleingang, einen differentiellen Messsignalausgang und einen Signalumsetzer. Der erste Messsignaleingang dient zum Empfangen eines ersten Eintakt-Messsignals, der zweite Messsignaleingang zum Empfangen eines zweiten Eintakt-Messsignals, wobei der Signalumsetzer dazu ausgebildet ist, bei Empfang eines ersten der Eintakt-Messsignale entweder das erste Eintakt-Messsignal oder das zweite Eintakt-Messsignal in ein kombiniertes differentielles Messsignal zu wandeln und an dem differentiellen Messsignalausgang bereitzustellen. Hierbei umfasst das differentielle Messsignal einen ersten dem ersten Eintakt-Messsignal zuordenbaren differentiellen Anteil und einen zweiten dem zweiten Eintakt-Messsignal zuordenbaren differentiellen Anteil.

A resistor-input transconductor includes a circuit configured to generate a common-mode compensation current. The common-mode compensation current is used to compensate for the common-mode voltage of the inputs. A current output of the resistor-input transconductor is proportional to a voltage difference between the two inputs and essentially independent of a common-mode voltage of the two inputs. The resistor input transconductor may be applied in a variety of applications including, for example, communications.

A circuit module for data processing comprises several first inputs (I x,i ), several second inputs (I y,i ) and several outputs (I i,j ). First transistors (T i,j ) combine the first and second inputs. Each of the first transistors (T i,j ) is connected at its emitter or source with a first input and at its base or gate with a second input. Each second input is further connected to the base or gate and the emittor or source of a second transistor (T i ). The currents of the outputs correspond to the product of the currents through the individual inputs. By combining the outputs sum products can be calculated, especially for computing discrete probability distributions. The combination of several circuit modules allows to solve complex signal processing tasks.
