Abstract

A defined zero point voltage (V.sub.0), dependent on a settable zero point voltage target value (V.sub.0,soll), is enabled in amplifier stages (1 . . . k) with neuron MOS transistors (T10,1 . . . T10,k). This is generally required because, for example, due to a process-caused charging of the floating gates of the neuron MOS transistors, and due to a capacitively coupled-in voltage from the channel region, an undefined zero point displacement of the transmission characteristic curve results. The devices can be used together with the amplifier stages, e.g. in video and audio technology, in sensor technology, in analog computers, in fuzzy circuits and in neural networks.
