Abstract
A circuit configuration for providing a capacitance includes short-channel MOS transistors that are reverse-connected in series or in parallel, and that have the same channel type. When the short-channel MOS transistors are operated exclusively in the depletion mode in the required voltage range, the useful capacitance is increased, because of intrinsic capacitances, as compared with circuit configurations having conventional long-channel MOS transistors. These circuits greatly reduce the area taken up and reduce the costs.
