Patent number: 8571137Abstract: Distortion and aliasing reduction for digital to analog conversion. Synthesis of one or more distortion terms made based on a digital signal (e.g., one or more digital codewords) is performed in accordance with digital to analog conversion. The one or more distortion terms may correspond to aliased higher-order harmonics, distortion, nonlinearities, clipping, etc. Such distortion terms may be known a priori, such as based upon particular characteristics of a given device, operational history, etc. Alternatively, such distortion terms may be determined based upon operation of a device and/or based upon an analog signal generated from the analog to conversion process. For example, frequency selective measurements made based on an analog signal generated from the digital to analog conversion may be used for determination of and/or adaptation of the one or more distortion terms. One or more DACs may be employed within various architectures operative to perform digital to analog conversion.Type: GrantFiled: August 31, 2011Date of Patent: October 29, 2013Assignee: Broadcom CorporationInventors: Thomas J.

Patent number: 7084800Abstract: A sequence mapping circuit and method for digital audio circuits generates a pulsed output. Over time, the mapping circuit generates pulses with a substantially identical average centroid for each of the possible output waveforms. For at least some of the output waveforms, two or more sets of pulses are provided representing the same waveform but having different centroids. The output is alternated among the available sets of pulses to maintain the desired average centroid over time. Shuffling of the output among the available pulses representing a given waveform may be randomly determined, or the pulses used may be tracked and the output pulses sequentially alternated among the available output pulses. The shuffled mapping method reduces output harmonics compared to conventional static mappers.Type: GrantFiled: January 30, 2004Date of Patent: August 1, 2006Assignee: Broadcom CorporationInventor: Kevin Lee Miller

Patent number: 7009542Abstract: An improved dither generation circuit and method for digital audio circuits uses a high-pass filter to reduce the energy contained in the audio band of the dither signal. The resulting dither signal is applied to the circuit in its main feedback loop and is effective to prevent idle tones. Because of its spectrally shaped characteristic this dither signal introduces less noise into the audio band of interest and thereby improves the overall signal-to-noise ratio of the audio circuit. In an embodiment, the dither signal is generated using pseudo-random numbers that are then interpreted as 2's complement numbers.Type: GrantFiled: November 2, 2004Date of Patent: March 7, 2006Assignee: Broadcom CorporationInventor: Kevin Lee Miller
