Patent number: 8791755Abstract: A self-oscillating driver circuit includes a driver stage, a feedforward path which is coupled to an input of the driver stage, and a feedback path which couples an output of the driver stage to an input of the feedforward path. The feedforward path includes a feedforward filter which is designed as an active filter. In order to prevent an oscillatory state of the driver circuit at an unwanted frequency, it is proposed that an internal state variable of the feedforward filter be monitored and that the feedforward filter be reset if the value of the monitored internal state variable is outside a predefined range.Type: GrantFiled: October 6, 2011Date of Patent: July 29, 2014Assignee: Lantiq Deutschland GmbHInventors: Dario Giotta, Thomas Poctscher, David San Segundo Bello, Andreas Wiesbauer

Publication number: 20110121888Abstract: Implementations related to compensating for on-current leakage associated with current source arrangements are disclosed. An implementation may be provided that includes a replicated current mirror output stage. A circuit may be disposed between a current mirror output stage and the replicated current mirror output stage. The circuit may be implemented to drive a voltage associated with the current mirror output stage to a voltage level associated with the replicated current mirror output stage. A current may be supplied by the circuit to drive the voltage associated with the current mirror output stage. In one implementation, the current is substantially equal to an on-current leakage associated with the current mirror output stage.Type: ApplicationFiled: November 23, 2009Publication date: May 26, 2011Inventors: Dario Giotta, Martin Clara

Patent number: 7084677Abstract: The invention relates to a line driver arrangement for driving signals via at least one subscriber line, provided with: an input for injecting an input signal and having an output at which a signal which is to be driven via the subscriber line can be tapped off, a digital amplifier which produces a pulse-width-modulated signal on the output side from the input signal or from a signal derived from it, an analog amplifier, which produces an analog signal on the output side from the input signal or from a signal derived from it, with the outputs of the amplifiers being coupled such that the signal to be driven results from superimposition of the analog signal and the digital signal, with the gain of the analog amplifier being matched to the gain of the digital amplifier such that scatter and/or overshoot on the digital signal are at least reduced after the superimposition.Type: GrantFiled: February 27, 2004Date of Patent: August 1, 2006Assignee: Infineon Technologies AGInventors: Thomas Ferianz, Christian Fleischhacker, Dario Giotta, Rüdiger Koban, Thomas Pötscher, Andreas Wiesbauer
