  • Patent number: 6965337
    Abstract: Systems and methods are disclosed herein to provide reference generators. For example, in accordance with an embodiment of the present invention, a reference generator is provided for an electrical device, such as for example for an analog-to-digital converter. The reference generator may provide one or more reference signals having a common mode voltage that can track or be varied based on a common mode voltage of an input signal. Alternatively or in addition, the reference generator may provide reference signals for single-ended applications.

  • Patent number: 6940352
    Abstract: A linear interpolator is provided that includes differential pairs of transistors biased such that a first input voltage may be multiplied by a factor r wherein 0?r?1 and such that a second input voltage may be multiplied by the complement factor (1?r). By combining the multiplied input voltages, a linear interpolation is provided based upon the factor r.

  • Patent number: 6940898
    Abstract: An adaptive coefficient signal generator for use in an adaptive signal equalizer with fractionally-spaced feedback. The signals representing the feedback tap coefficients are generated in conjunction with a timing interpolation parameter such that the fractionally-spaced feedback circuitry dynamically emulates symbol-spaced feedback circuitry.

  • Patent number: 6922440
    Abstract: An apparatus and method for adaptively introducing a compensating signal latency related to a signal latency of a data symbol decision circuit. Adaptive timing control circuitry, including an interpolating mixer implemented as a tapped delay line with correlated tap coefficients, introduces a latency adaptively and substantially matching the latency of the data decision circuit for use within an adaptive equalizer, thereby minimizing the mean-squared error of such decision circuit. This adaptive latency is used in generating the feedback error signal which, in turn, can be used by the feedforward equalizer for dynamically adjusting its adaptive filter tap coefficients.
