Abstract
The invention relates to a procedure and a circuit device for the subtraction of electrical signals, with at least two regulating loops each comprising at least one amplifier unit. Advantageously, the circuit device comprises a device for subtracting a signal, made available by the circuit device and representing the difference between the electrical signals, from one of the electrical signals. In a preferred embodiment of the invention, the potentials on lines carrying the electrical signals are maintained at the same value with the help of a first one or of the regulating loops.
