  • Publication number: 20130170582
    Abstract: The frequency response of a digital filter, such as a pre-emphasis filter in a signal transmitter having a phase-locked loop, is adjusted using interpolation of the filter coefficients, enabling sets of filter coefficients to be pre-computed or generated as needed in the transmitter. The phase error behavior of the digital filter can be significantly improved.

  • Publication number: 20130057334
    Abstract: Embodiments described in the present disclosure relate to a method for providing power for an integrated system, including acts of: providing the system with power, ground and body bias voltages, the body bias voltages comprising a body bias voltage of p-channel MOS transistors, greater or lower than the supply voltage, and a body bias voltage of n-channel MOS transistors, lower or greater than the ground voltage, selecting by means of the system out of the voltages provided, depending on whether a processing unit of the system is in a period of activity or inactivity, voltages to be supplied to bias the bodies of the MOS transistors of the processing unit, and providing the bodies of the MOS transistors of the processing unit with the voltages selected.

  • Publication number: 20130027010
    Abstract: A voltage regulator includes a current bridge and first and second current paths coupling a current mirror to respective first and second voltage-to-current converters. The current mirror controls a second current dependent on a first current. The first voltage-to-current converter controls the first current dependent on either a reference voltage or a feedback voltage derived from the regulator's output voltage, and the second voltage-to-current converter controls the second current dependent on the other of the feedback and reference voltages. Voltage-to-current conversion by the first converter is independent of voltage-to-current conversion by the second converter. An output transistor stage coupled to the second current path controls the output voltage dependent on the voltage in the second current path indicative of a deviation of the second current from a target current value dependent on the reference voltage.
