    Abstract: A comparator comprises a differential amplifier (T1, T2, T8, T9) having differential inputs (IN1, IN2) forming the comparator inputs, and a first and a second amplifier output (f1, f2) forming the comparator outputs of a first comparator stage, wherein the differential amplifier has first (T1, T8) and second (T2, T9) parallel branches. The comparator has a first current source circuit (32) defines a current to be driven through the differential amplifier, a second current source circuit (34) comprising a load driven by the first branch and a third current source circuit (36), comprising a load driven by the second branch. Circuitry (T6,T7) is provided for defining the voltage difference between the first and second amplifier outputs when the differential amplifier is in a stable state providing a differential output. This arrangement drives current through the two branches independently, so that the main transistors in each branch can be kept on to enable rapid response times.

  • Patent number: 7579900
    Abstract: Since parallel MOSFETs are usually driven with one gate signal in power applications, the current sharing between the MOSFETs is automatically established with regard to the characteristics of the individual MOSFETs. This may lead to a large non-uniformity of the current distribution between the MOSFETs. According to the present invention, an individual control of the on-resistances of the MOSFETs is provided, which allows for an improved current sharing between paralleled MOSFETs.

  • Patent number: 7579968
    Abstract: A data processing circuit comprises an encoder circuit for encoding a data word, wherein each digit may have any one of three or more digit values. The data word is encoded so that digit counts in the data word satisfy predetermined criteria (the digit counts are counts of the numbers of the digits in the encoded data word that assume respective digit values). The encoder defines at least two digit maps, each digit map defining assignments of each of the available digit values to a respective different output digit value. The encoder selects at least two groups of digits within the input data word. Each group is associated with a respective one of the digit maps, the groups being selected so that when each digit map has been applied selectively to the digits from its associated group, digit counts of the number of times respective digit values occur in the data word will satisfy predetermined criteria.

  • Patent number: 7580489
    Abstract: A rake receiver tracks a component of a multipath information signal transmitted over a communication network. The rake receiver aligns and synchronized the component with a locally generated replica of the code sequence that was originally used to spread the information signal at the transmitter side. The rake receiver derives an early de-spread signal using an early shifted version of the replica of the code sequence. The replica is early shifted by a variable delay. The rake receiver also derives a late shifted de-spread signal using a late shifted version of the replica of the code sequence. The replica is late shifted by the same variable delay. The variable delay may be chosen arbitrarily or among a selection of predetermined values. The predetermined values may be selected so that the tracking process is optimized.

  • Publication number: 20090206940
    Abstract: The present invention relates to a polar signal generator and method of deriving phase and amplitude components from in-phase (I) and quadrature-phase (Q) components of an input signal, wherein the I and Q components are generated at a first sampling frequency based on the input signal, and are then up-sampled in accordance with a predetermined first interpolation factor (N), to generate up-sampled I and Q components at a second sampling frequency higher than the first sampling frequency. The up-sampled I and Q components are converted into the phase and amplitude components, wherein the converting step is operated at the second sampling frequency. Moreover, the phase and amplitude components can be further up-sampled, optionally by different sampling frequencies, to a third and a fourth sampling frequency. Thereby, I-Q generation and cartesian-to-polar transformation can be performed at lower frequencies, which reduces power consumption.
