A digital neural network has a plurality of neurons (NR) completely meshed with one another, each of which comprises an evaluation stage having a plurality of evaluators (B) that is equal in number to the plurality of neurons (NR) and each of which comprises a decision stage having a decision unit (E). An adjustment information (INF.sub.E) that effects a defined pre-adjustment of the decision unit (E) can be supplied to every decision unit (E) by a pre-processing means via an information input. A weighting information (INF.sub.G) can be supplied to every evaluator (B) by a pre-processing means via an individual information input. An output information (INF.sub.A) can be output by every decision unit (E) to a post-processing means via a respective individual information output. The information outputs of the decision units (E) are each connected to an individual processing input of all evaluators (B) allocated to the appertaining decision unit (E). Individual processing outputs of the evaluators (B) are connected to individual processing inputs of the decision unit (E) in the appertaining neuron (N), so that every output information (INF.sub.A) can be indirectly fed back onto every neuron (NR).

The differential amplifier has two n-channel or p-channel field effect transistors serving as controllable current sources which supply auxiliary currents upon appearance of an input signal which amplify the quiescent current. The inputs of the differential amplifier are connected to the gate terminals of the n-channel or p-channel field effect transistors via a level-converting circuit for converting the d.c. component of the input signal superimposed on a gate bias voltage to a lower or, respectively, higher output level. As a result of the control of the current sources proceeding from the amplifier input good driver qualities, a distortion-free signal transmission and a lower dissipation power are guaranteed.

An integrated circuit in complementary circuit technology comprising two field effect transistors (T1, T2) of different channel types with the first one (T2) mounted in a doped semiconductor body (1) having a first conductivity type and the other FET (T1) mounted in a semiconductor zone 2 of a second conductivity type which is arranged in said body. The object is to provide a protection against thermal overloads which can appear due to "latch up" influences when overvoltages at the one connecting region of the field effect transistor (T1) mounted in the semiconductor zone occur. This is accomplished by the mounting of a metal contact (12) on the surface of a semiconductor region (2') inserted into the semiconductor body 1 and doped oppositely thereto with such metal contact forming a Schottky diode (D) with the semiconductor region (2') which can be connected to the connecting region of the field effect transistor T1 mounted in the semiconductor region 2 whereas the semiconductor region (2') is electrically connected to the supply voltage (V.sub.DD). The circuits are applied in CMOS circuits.
摘要:
Video signals are stored on a continuously movable magnetic tape with a dissection of the video signals into a plurality of partial signals and simultaneously recording the partial signals in a plurality of longitudinal tracks which extend parallel to one another. Inasmuch as mutual influences of the individual image formation to be stored are to be reduced, even given a great recording density, the signal lines of the video signal are employed as partial signals, whereby the line signals belonging to a television image are combined to at least one group and are successively recorded in groups. All line signals belonging to one and the same group are simultaneously recorded on a plurality of longitudinal tracks after an intermediate storage. The invention finds particular application in video recorders having longitudinal track recording.
摘要:
In illustrated embodiments, at least one analogue shift register has a number of parallel inputs and one series output. A number of individual evaluating circuits receive the signal to be filtered and supply respective output quantities of charge equal to the product of the difference between the relevant signal value and a predetermined minimum or maximum value, and a respective individual evaluation factor. The output of each evaluating circuit can be connected via a switching element to an associated parallel input. The capacity of every storage position of the shift register is at least such that it is always able to accommodate the maximum quantity of charge supplied by the preceding storage position, and when the storage position has a parallel input, can additionally accommodate the maximum quantities of charge supplied by the associated evaluating circuit (s). Various modifications are disclosed for reducing the space requirement of a transversal filter when implemented, for example, as a CCD.

An information memory for storing information in the form of electric charge carriers has at least one dynamic storage element which is arranged upon a surface of at least one substrate made of semiconductor material and doped with a given basic type doping. The substrate connection is included and the memory comprises at least one MIS capacitor. Upon the substrate surface at least one electrically insulating layer is present which carries at least one capacitor electrode. The dynamic storage element comprises the MIS capacitor or an adjacent arrangement of several MIS capacitors, separated from one another by, at the most, narrow distances and comprises at least one contact area at the substrate surface which is provided with an externally accessible ohmic terminal contact, and which contacts at least the margin of the MIS capacitor or t least one of the MIS capacitors, nd which contains material having the basic type of doping. Within the electrically insulating layer, within the MIS capacitor or capacitors, the values of the numerical ratio .epsilon./d--whereby .epsilon. is the dielectric constant and d is the layer thickness of the electrically insulating layer--and/or the values of the surface density of the basic type of doping of the substrate in the area or in the areas of the MIS capacitor or capacitors and/or the values of the surface density, with respect to the surface of the substrate, of and adjacent to the substrate and doped opposite to the type of doping of the substrate layer, are selected differently with respect to location in such a way that, by the way of applying an electrode voltage, which may be given within a wide range between the substrate terminal and electrode, the local distribution of the amounts of the potential maximum between the range or within the ranges of the MIS capacitor or capacitor, comprises, laterally away from the contact area beginning at the side of the contact area, at least one increase from a minimum value to a maximum value.
摘要:
Memory cells are disclosed that avoid the utilization of analog circuits in the memory peripheral circuits when they are utilized in static memory modules and that intended to enhance the disturbed reliability when confronted by technology modifications and parameter fluctuations. Write-in thereby occurs from a write data line via a write selection transistor and read-out occurs via a read selection transistor onto a read data line. A second inverter formed of two field effect transistors serves as a feedback element in order to statically maintain the cell information. Due to an implemented asymmetry in the dimensioning between the first and second inverters, the memory cell is significantly less susceptible to information loss upon read-out when compared to a heretofore known memory cell. A precharging of the read data line is not required with these memory cells.
摘要:
A function check of a programmable logic array is performed in which input lines, product term lines and ground lines are combined into an AND plane and output lines, product term lines and ground lines are combined into an OR plane. The aim is a simple method of function check which permits any potentially-existing fault to be detected. The check is achieved by generating, with a test data generator, bit patterns and applying the same to the input lines, and, through the use of a shift register, successively sensitizing the product term lines either individually or in groups, i.e. disconnecting the same from ground potential. The bit patterns occurring at the output lines are supplied to a test data evaluator. The area of use is in logic circuitry of data processing technology.
