  • Analogue echo filter
    Patent number: 6947478
    Abstract: The invention relates to an analog echo filter for a modem, to which an analog transmit signal is supplied. According to the invention, a passive analog input filter and an active analog filter, whose transfer function is adjustable, are provided. The transfer function of the active analog filter can preferably be switched between a first-order transfer function and a second-order transfer function.

  • Multistage differential amplifier with CMFB circuit
    Patent number: 6888407
    Abstract: The invention relates to a multistage differential amplifier having an input stage, at which a differential input voltage is present, a load connected to the input stage, a CMFB circuit and an output stage, at which an amplified differential output voltage is output. In order to improve the stability of a common-mode regulating loop, a current source is provided, which additionally feeds current into the regulating loop and thereby ensures that a control voltage for the load does not fall below a predetermined value.

  • SD-ADC with digital dither signal processing
    Patent number: 6738002
    Abstract: A sigma-delta analog-to-digital converter includes an integrator and a dither signal generator for generating a digital dither signal, and a plurality of comparators for converting an analog signal received from the integrator into an output digital value. A digital logic unit is in data communication with the digital dither signal and the comparators. The digital logic unit is configured to change the output digital value on the basis of the digital dither signal.
