摘要： Systems and methods for improving efficiency of a data converter. An example method generates a noise signal, alters the spectrum of the noise signal based on operation of an associated data converter, and supplies the altered spectrum noise signal to the associated data converter. The data converter is a digital-to-analog converter or an analog-to-digital converter. The altered spectrum noise signal is notched at frequencies of interest. The spectrum is altered by sending a signal generated by a random number generator to a delay device and adding the output of the delay device from the output of the random number generator. Also, the spectrum is altered by seeding first and second identical random number generators, delaying the operation of the first random number generator, and adding the output of the delayed first random number generator from the second random number generator.

摘要： An A/D converter system has an A/D converter element (10) which provides a first predetermined number of digital output bits for each input analog signal, an addition means (12,70) for adding linear slope potential to said input analog signal, and a calculator (14) for providing an average of a plurality of digital output signals of said A/D converter element so that said average has larger number of bits than said first predetermined number. Said addition means is implemented by a time constant circuit (70) which functions as an integral circuit for an input analog signal, and functions as a differential circuit for a slope potential.

摘要： A sample and hold circuit (10) receives a low level analog input signal and is gated by a clock (18). The output of the sample and hold circuit (10) is summed with a signal from a noise source (22) and the resulting signal coupled to an analog to digital (A/D) converter (24). The noise source (22) presents a bandwidth restricted signal having no substantial energy in the range of frequencies of the desired analog input signal. The clock (18) also drives the A/D convertor (24) which has a plurality of digital output signals (26) which correspond to varying analog signal levels. The resulting signal contains a signal component corresponding to the input signal which is converted into a digital representation by the A/D convertor (24) even though the magnitude of the input signal is less than the threshold sensitivity of the A/D convertor (24).

摘要： A system and method for enhancing a dynamic range of a beamforming multichannel digital receiver are described. The receiver comprises a plurality of receiving channels, each including an analog-to-digital converter configured for converting an analog input signal generated by antenna elements into a digital signal. A "spatial" dither signal is used to decorrelate the quantization noise of the analog-to-digital converters. A dither signal is generated and split into a predetermined number of coherent dithering signals. The method includes providing predetermined time delays to the coherent dithering signals, and adding the delayed coherent dithering signals to the input signals in each receiving channel, correspondingly, thereby creating a dither signal equivalent to a signal arriving from a certain specific direction out-of-field-of-view of the antenna array. Removing of the dither signal based on the direction of arrival, is implemented during beamforming signal processing, thus enhancing the dynamic range of electromagnetic signals arriving within a field-of-view of the antenna array.
