20080224694 | Semiconductor component and method for testing such a component - A semiconductor component on a semiconductor chip comprises at least one sensor element for measuring a physical quantity and an evaluator. The semiconductor component can be switched between a first and a second operating mode. In the first operating mode, the sensor element is sensitive to the physical quantity to be measured and a measurement signal output of the sensor element is connected to an input connection of the evaluator. In the second operating mode, the sensor element is not sensitive to the physical quantity to be measured and/or the signal path between the measurement signal output and the input connection is interrupted. A test signal source for generating a test signal simulating the measurement signal of the sensor element is arranged on the semiconductor chip. In the second operating mode, the test signal source is connected or capable of being connected to the input connection of the evaluator. | 09-18-2008 |
20090079420 | INTEGRATED ELECTRONIC CIRCUIT - Disclosed is an integrated electronic circuit comprising a core circuit that generates a useful signal as well as a buffer for storing the useful signal. The buffer stores the last read value of the useful signal for a predetermined period of time when the power supply is interrupted, and the buffer is disconnected from the power supply of the other circuits. | 03-26-2009 |
20090152548 | Semiconductor Component - 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.

20090180497 | Communication Device and Method for Data Transmission - Disclosed is a method and device for transmitting data between at least two transmitters and a receiver which are connected to a bus. A synchronization signal is applied to the bus and a number of data volume counters corresponding to the number of transmitters reduced by one is set to a predefined initial value. A first transmitter transmits in the form of data elements a predefined data volume allocated to the transmitter over the bus to the receiver. The data volume values of the other transmitters are selected so that only one transmitter at any given time simultaneously transmits on the bus. | 07-16-2009 |
20090295614 | DIGITAL-TO-ANALOG CONVERTER CIRCUIT LAYOUT - 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. | 12-03-2009 |
