Abstract
Stacked slab-shaped support bodies of electrically insulated material are provided with electrodes at one of their side surfaces. In the stack, the electrodes of a support body form the rows of a matrix. The support bodies are each connected detachably to a circuit board on which switchable amplifiers are arranged. In a preferred embodiment, the switchable amplifiers are dual-gate MOS-FETs, the first gate terminals of which are each connected electrically to an electrode of the support body.
