A system adapted to regulate a voltage of a supply bus is described. The digital communication receiver has a controller, which receives channel quality indicative data associated with an output from the equalizer, determines whether these data fail to meet a predetermined criterion, and, if so, supplies an enabling control signal to the channel tracker. In case of a forthcoming adjustment of the at least one gain factor by the gain control, the compensation quantity is then scaled with a scaling factor to prevent a direct-current step at the selected end point due to this forthcoming adjustment. The distal end of the device is removably insertable in the biological substance relative to the interior structure to be visualized and is composed of a biologically stable substrate material. The electronic component further includes an electric conduction plug, which penetrates from the first surface to the second surface of the semiconductor substrate, and which is electrically connected to the electrical mechanical element.
