  • Patent number: 7536431
    Abstract: An integrated VMM (vector-matrix multiplier) module, including an electro-optical VMM component that multiplies an input vector by a matrix to produce an output vector; and an electronic VPU (vector processing unit) that processes at least one of the input and output vectors. Various error reducing mechanisms are also discussed.
    Type: Grant

  • Patent number: 6232903
    Abstract: A noise cancellation circuit for use with a digital signal includes a plurality of equally weighted cells (53) for providing an analogue output signal (35) in dependence upon the value of the digital signal. A switching arrangement (51) dynamically switches a number of the plurality of cells according to a sequencing scheme, which comprises a first sequence arranged to switch each of the plurality of cells (53) an equal number of times, and a second sequence arranged to define one of the plurality of cells (53) as a starting position for the first sequence. In this way low frequency tone generation within the analogue output signal is substantially eliminated.

  • Patent number: 5724038
    Abstract: A noise cancelling circuit (10) is used with a D/A converter, the converter including a first modulator (11) and a data output. The circuit (10) has an error measuring arrangement (12, 13, 14) for measuring a quantization error signal of the modulator (11). A filter (19) receives the error signal end provides a fired error signal. A filter compensator (17) is coupled to the data output and provides a compensated output. A scaler (15) is coupled to receive the filtered error signal and provides a scaled filtered error signal. A second modulator (16) is coupled to receive the scaled filtered error signal and provides a single bit stream of error data. A summing arrangement (18) sums the single bit stream of error data and the compensated output from the first modulator and provides a corrected output, such that the error signal is filtered, sealed and modulated end the data output is compensated such that the corrected output is obtained having a substantially reduced quantization error.
