Arrangement for distortion-free amplification of electrical voltages with full electrical isolation forms output voltage by superimposing input voltages with adjustable output factor

摘要

The arrangement forms an output voltage by superimposing the input voltages, whereby the output voltage is different from the sum of the input voltages by an adjustable factor. It contains parallel pairs of MOS transistors with floating gates and a controller that adjusts the transistor working points to compensate for deviating component parameters. Independent claims are also included for the following: an arrangement for summing and amplifying signals, an arrangement for adding sinusoidal voltages, an arrangement for generating a rectangular voltage, an arrangement for generating a sinusoidal voltage, an arrangement for regulating an electrical parameter, an arrangement for controlling a central alignment of a light source and n arrangement for generating very short voltage pulses.
