Patent number: 7816907Abstract: An integrated circuit includes an output terminal to be coupled to a light-emitting diode, an output circuit coupled to the output terminal, the output circuit being configured to supply an operating signal to the light-emitting diode, a measuring circuit coupled to the output terminal and a control circuit coupled to the measuring circuit. The measuring circuit is configured to sense on the output terminal a signal value outside an operating regime of the light-emitting diode, the signal value being a voltage below a forward voltage of the light-emitting diode or a current below a threshold current of the light-emitting diode. The control circuit is configured to configure at least one function of the integrated circuit when the signal value as sensed by the measuring circuit corresponds to a voltage below the forward voltage of the light-emitting diode or a current below the threshold current of the light-emitting diode.Type: GrantFiled: April 23, 2008Date of Patent: October 19, 2010Assignee: Lantiq Deutschland GmbHInventors: Christoph Schwarzer, Holger Wenske, Mario Träber, Thomas Eichler, Marc Hesener, Armin Hanneberg, David Herbison

Patent number: 7450649Abstract: The invention relates to a transmitter for transmission of digital data via a transmission line (10), comprising a current-driving digital/analogue converter (1) which is arranged at the input of the transmitter; a current-operated form filter (2) for forming the current pulses which are supplied from the digital/analogue converter; a line driver (5) which carries out current/voltage conversion; and a circuit for offset compensation (6), which is arranged in a feedback path (11). In order to improve the quality of the pulses which are transmitted at the output of the transmitter, the invention proposes that the internal signal processing of the transmitter be carried out on a current basis.Type: GrantFiled: May 15, 2003Date of Patent: November 11, 2008Assignee: Infineon Technologies AGInventors: Peter Gregorius, Armin Hanneberg

Patent number: 7030660Abstract: A line driver which is especially suitable for wirebound data transmission at high bit rates, comprising several parallel-connected driver stages (3) respectively comprising a first pair of transistors consisting of two transistors (4, 5) which are controlled in a differential manner according to digital data to be transmitted, and a second pair of transistors (4, 5). The transistors belonging to the second pair of transistors (6, 7) are series-connected to a corresponding transistor (4, 5) of the first pair of transistors. The individual driver stages (3) are connected by the transistors (6, 7) of the second pair of transistors in a parallel manner to both the terminals of the line driver. Each driver stage (3) is associated with a control circuit (2) with transfer gates (14, 15), producing the differential control signals (VGA, VGB) for the two transistors (4, 5) of the corresponding first pair of transistors.Type: GrantFiled: June 11, 2002Date of Patent: April 18, 2006Assignee: Infineon Technologies AGInventors: Armin Hanneberg, Peter Laaser

Patent number: 6522707Abstract: Disturbances in bipolar signals transmitted on a transmission line are suppressed by adjusting the amplitude of the signals with coarse adjustment steps and with fine adjustment steps. The amplitude adjusted signals are compared to at least a lower reference level and an upper reference level for determining a first percentage of the amplitude adjusted signals violating the lower reference level and a second percentage of the amplitude adjusted signals violating the upper reference level. The coarse adjustment steps and the fine adjustment steps are selected in accordance with an adjustment characteristic which evaluates at least the first percentage and the second percentage. The adjustment characteristic is changed if a tendency of reference level violation of the amplitude adjusted signals is detected and a check is performed if the step of changing the adjustment characteristic improves the disturbance suppression. A device for suppressing disturbances is also provided.Type: GrantFiled: April 30, 1999Date of Patent: February 18, 2003Assignee: Siemens AktiengesellschaftInventors: Markus Brandstetter, Armin Hanneberg

Patent number: 5925905Abstract: The MOS circuit configuration allows switching high voltages on a semiconductor chip. In order to switch a high negative voltage, for example as a programming voltage on the word line of a flash-memory, two circuit variants are given which are formed only with transistors of the same conductivity type as the substrate. The substrate and the transistors formed in the well are p-conductive. In this way it is possible to dispense with deep insulating wells which require special technology.Type: GrantFiled: July 24, 1997Date of Patent: July 20, 1999Assignee: Siemens AktiengesellschaftInventors: Armin Hanneberg, Georg Tempel
