  • Patent number: 7099218
    Abstract: A differential current evaluation circuit has a differential amplifier and a circuit for setting an input resistance of the current evaluation circuit. The circuit is connected to the outputs and the inputs of the differential amplifier and to signal lines. A sense amplifier circuit has a circuit section, in which a signal is available at an output in a temporally continuous manner even if, after the deactivation of the circuit connected upstream, a signal, in particular a signal supplied by the current evaluation circuit, is no longer present at its input. The differential current evaluation circuit and the sense amplifier circuit are disposed in a circuit configuration for reading out and evaluating a memory state of a semiconductor memory cell. The current evaluation circuit can be activated by a circuit section for automatic deactivation before a read operation and be automatically deactivated directly after the read operation has ended.

  • Patent number: 6700149
    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.
