摘要： An analog-to-digital converter provides for reduced complexity and power consumption along with improved linearity. The analog-to-digital converter has a reduced number of quantizer output levels and includes a loop filter, a quantizer for quantizing the output of the loop filter and a digital integrator for integrating the output of the quantizer. A difference circuit is included in the converter that produces a signal proportional to the difference between the present value and a previous value of the digital integrator output and provides feedback to the loop filter. The number of levels of the quantizer output is thereby reduced with respect to the modulator output, since the quantizer is operating on a feedback signal that represents changes in the output of the converter modulator rather than the modulator output itself.

摘要： A multilayer substrate module to which an external ground node (20) supplies a reference ground potential (Vss) includes a plurality of ground lines (170-1, 170-2, 170-3), which correspond to a plurality of internal circuits (210, 220, 230), respectively. A common node (Ncmn) for joining the ground lines (170-1, 170-2, 170-3) is provided in an insulating layer (105C) in the multilayer substrate module. The common node (Ncmn) is coupled electrically to the ground node (20) through a ground pin terminal (204) shared among the internal circuits (210, 220, 230). The common node (Ncmn) is provided preferably in the lowermost insulating layer in the multilayer substrate module (120). The parasitic inductance appearing in a ground current path and shared among the internal circuits (210, 220, 230) can be decreased using fewer ground pin terminals. Therefore, the ground current path is prevented from being circuitous among the internal circuits (210, 220, 23O), resulting in stabilized operation.

摘要： A multi-bit continuous-time sigma-delta modulator, SDM, includes an input configured to receive an input analog signal; a first summing junction configured to subtract a feedback analog signal from the input analog signal; a loop filter configured to filter an output signal from the first summing junction (304): an analog-to-digital converter, ADC, configured to convert the filtered analog output signal to a digital output signal; and a feedback path for routing the digital output signal to the first summing junction. The feedback path includes a plurality of digital-to-analog converters, DACs, configured to convert the digital output signal to an analog form. The ADC comprises a plurality of N-bit comparator latches that are each locally time-interleaved with at least a pair of latches and configured to function in a complementary manner and provide a combined complementary output.

摘要： A phase-domain delta-sigma (ΔΣ) modulator in a phase digitizer determines a demodulated phase error based on a phase-modulated frequency signal, in which a carrier frequency is modulated with a fundamental frequency and an associated phase, and a selected one of a set of reference signals, where the demodulated phase error represents a difference between the phase and a reference phase of the selected one of the set of reference signals. Moreover, a digital filter in the phase-domain ΔΣ modulator filters the demodulated phase error. Furthermore, a latch in the phase-domain ΔΣ modulator provides a bit stream by sampling one or more bits of the filtered demodulated phase error, where an average value of the bit stream represents the phase. Next, control logic in the phase-domain ΔΣ modulator selects the one of the set of reference signals.

摘要： An apparatus and method for reducing error in converting a multi-bit signal to a single bit signal. An analog delta-sigma modulator receives an analog signal and converts it to a multi-bit digital signal that is provided to a digital delta-sigma modulator. The digital delta-sigma modulator introduces error by converting the multi-bit signal to a single-bit signal. The error from the conversion is fed back to the analog delta-sigma modulator which incorporates the error information into the analog signal before it is converted to a multi-bit digital signal.
