摘要:
A mount for a programmable electronic processing device is disclosed. It is divided into at least a first functional unit (7) and a second functional unit (8) which represent separate, particularly monolithic integrated, components. The first functional unit (7) defines all input and output interfaces of the processing device with respect to their electrical properties. All essential connections of the second functional unit (8) are accessible from outside only via the first functional unit (7). To this end, the first functional unit (7) includes matching circuits which serve to electrically adapt the connections of the second functional unit (8) to the external conditions.
摘要:
A digital control circuit with a device for generating a high-resolution tuning voltage is suitable for use in receivers for RF signals, particularly in consumer equipment. The tuning voltage can be electronically switched from one value to another at a high speed. The transient time required with conventional control loops is nearly eliminated since the low-pass filter or the digital integrator is preset to its steady-state integration value. To generate the tuning voltage, dynamic digital-to-analog convertors are provided which, despite their high resolution, require only a smoothing filter with a short response time and a short time constant.
摘要:
A processing device embodied in an integrated circuit may be divided into first and second functional units. A mount for the integrated circuit may be assigned to the first functional unit, which may define the external electrical connections of the processing device. Processing may take place in a second functional unit of the processing device, whose essential connections may normally be accessible from outside via the external connections of the first functional unit. The processor device having first and second functional units in a mount may be similar to a hybrid circuit but may serve a different purpose. The first functional unit, which may also comprise more than one monolithic integrated circuit, may define the external connections and may make available suitable matching circuits for the second functional unit. In this manner, the processing device, which may be contained in the second functional unit and may also comprise more than one monolithic integrated circuit, may be considered to be “masked” as viewed from outside. In addition to the matching circuits, the first functional unit may contain subcircuits performing more general functions, such as oscillators, supply voltage regulator circuits, buffer circuits, protective circuits, etc.

摘要:
In an electrooptical arrangement for remotely controlling an electronic apparatus with a remote control transmitter, the transmitter is formed with three sources of radiation whose radiation patterns are different from each other and can be comparatively detected relative to each other to indicate the tilting of the transmitter in different reference plane directions. A radiation detector at the receiver side detects the different radiation intensities for the signals from the three sources, and the relation between the signal intensities is evaluated to determine the tilt angles of the remote control transmitter in the reference plane directions.

A measuring apparatus for detecting a relative movement between at least one magnetic field sensor array integrated into a semiconductor chip and a transmitter for the sensor array is provided. The transmitter and the sensor array are exposed to the magnetic flux of a magnet. The transmitter has teeth that can be moved past the sensor array during the relative movement, or the transmitter has magnet poles that can be moved past the sensor array during the relative movement. The magnetic field sensor includes a differential magnetic field sensor which comprises a first measuring plate and a second measuring plate that are offset in relation to one another in a direction of the relative movement. The magnetic field sensor also includes a sensor element which is designed to measure the absolute magnetic field and comprises a third measuring plate that is arranged between the first measuring plate and the second measuring plate in the direction of the relative movement.

In a method for generating pulse edges, assigned synchronously to the movement of a mechanical part, a magnetic field is generated. At least two measuring signals phase-shifted to one another for the magnetic field are detected. The magnetic field is changed as a function of the movement of the mechanical part in such a way that the measuring signals are modulated. A first measuring signal is compared with at least one first reference value. A second measuring signal is compared with at least one second reference value and/or the value of the first measuring signal is compared with the value of the second measuring signal. When at least one of these comparisons produces an agreement or the result of the relevant comparison changes its sign, a pulse edge is generated.

A digital-to-analog converter circuit layout includes a ratiometric digital-to-analog converter. The ratiometric digital-to-analog converter includes a digital data input, a converter voltage output, a voltage controlled oscillator, and a pulse width modulation module. The a digital data input, a converter voltage output, a voltage controlled oscillator, and a pulse width modulation module is configured in a controllable manner for converting digital data received at the input to a converter output voltage at the output using a reference voltage, an adjustable current as a reference current, and an adjustable impedance value. The circuit layout is characterized in that the voltage controlled oscillator includes circuit components which multiply the reference voltage by a quotient between the adjustable impedance value and the adjustable current, and which apply the multiplication results to the pulse width modulation module.

A semiconductor component (has at least one semiconductor chip in which an electrical circuit is integrated. The semiconductor chip is surrounded by an electrically insulating encapsulating compound and has on its surface at least one termination surface for a test signal, which is covered by the encapsulating compound. The termination surface is connected in an electrically conductive manner to an analysis contact that projects above the surface of the semiconductor chip, that is located in the interior of the encapsulating compound at a distance from its exterior surface, and that can be exposed by removing a layer of the encapsulating compound located near the exterior.
