A method is provided in which several rules having an identical conditional part and different consequence parts are processed more quickly in that the fuzzification and at least parts of the inference formation are carried out only once, and in which the storage capacity of a knowledge base memory can be reduced, since all identical conditional parts need be stored only once.

Method for multiple use of a rule base in a fuzzy logic coprocessor

An ordering method for ranking membership function values (Wi) of linguistic input values (LWEi) in a fuzzy logic processor is presented The steps of the method are:

Method for ranking membership function values of linguistic input values

A voltage generator circuit includes a storage capacitor with a terminal for pickup of an output voltage. A voltage generator device which can be turned on and off has an output being connected to the terminal of the storage capacitor. A first comparator device which can be turned on and off compares the output voltage with a first threshold voltage and generates a signal for turning the voltage generator device on and off. A second comparator device compares the output voltage with a second threshold voltage and generates an output signal with which the first comparator device is turned on and off.

A charge pump assembly includes a storage capacitor having one terminal for a first supply potential and another terminal for pickup of an output potential. The assembly has one charge pump or two charge pumps being controlled by push-pull signals. Each charge pump includes a p-channel MOS transistor having a gate terminal being controlled by a first signal and having a drain-to-source path with one terminal being connected to the other terminal of the storage capacitor. A sliding capacitor has one terminal being connected to the other terminal of the drain-to-source path of the p-channel MOS transistor and another terminal being controlled by a second signal. An n-channel MOS transistor has a gate terminal being controlled by a third signal and a drain-to-source path being connected between a second supply potential and the one terminal of the sliding capacitor. A pulse shaper device is supplied by an oscillator device for generating the signals, in such a way that the p-channel MOS transistor is conducting only whenever the second signal is at a high level, and the n-channel MOS transistor is conducting only whenever the second signal is at a low level.

A regulating circuit for a substrate bias voltage generator for generating a substrate bias voltage in an integrated semiconductor circuit includes a Schmitt trigger circuit disposed between a first potential and a second potential of a semiconductor circuit. The Schmitt trigger circuit has an output side and an input for controlling a hysteresis function of the Schmitt trigger circuit. An inverter array is connected downstream of the output side of the Schmitt trigger circuit. The inverter array is connected to the first potential and to a first supply potential of the semiconductor circuit in terms of supply voltage, and the inverter array has an output. The input of the Schmitt trigger circuit for controlling the hysteresis function of the Schmitt trigger circuit is connected to the output of the inverter array.

A conductor track configuration for very large-scale integrated circuits includes at least two lower conductor tracks extending substantially in a first direction and at least two upper conductor tracks extending substantially in the first direction above the lower conductor tracks. Each of the lower conductor tracks is subdivided into segments, defining gaps between the segments. Each respective one of the segments has one contact leading to the upper conductor track disposed above the one segment. The lower conductor tracks adjacent the segments, as seen in a second direction, have one of the gaps at least in the vicinity of one of the contacts.
