The invention relates to a doped organic semiconductor material with increased charge carrier density and more effective charge carrier mobility, which may be obtained by doping an organic semiconductor material with a chemical compound comprising one or several organic molecular groups and at least one further compound partner. The gaming network has a plurality of servers dedicated to providing a shared game to a plurality of gaming terminals. A processor is connected to the output of the digital-filter system so that the processor transparently receives filtered sample data in the native format of the analog-to-digital converter. A charge switch is operable to receive a DC voltage input and generate a switched IDC voltage output having the first switching frequency.
