Abstract: Methods and apparatus for shaping and filtering quantization errors conjointly in space and time to produce a higher-precision output in a spatially and temporally oversampled array. A space-time error-shaping array system has an array of sensors, each sensor producing a temporal signal comprising quantized waveforms. A multi-input multiple-output (MIMO) discrete-time filter structure with multiple inputs, each coupled to a sensor of the array of sensors, shapes quantization errors of the array of sensors on the basis of temporal aspects of the quantized waveforms conjointly with spatial aspects of the quantized waveforms.

Abstract: An adaptive Analog to Digital Converter (ADC) that adjusts the representation levels used in the conversion process so as to optimize system performance. By establishing system performance criteria by which to select or adjust the signal value range associated with each digital representation and/or the digital representation, substantially fewer bits may be used in the ADC. The systems and methods described herein enable lower-power, smaller form-factor designs as well as very high-speed operation. In particular, this technology may be beneficial for use in communications systems because it enables ADC's to operate at speeds where traditional ADC designs simply cannot.
