Pipelined Hybrid Noise-Shaping Analog-To-Digital Converter - A simplified explanation of the abstract

This abstract first appeared for US patent application 17847302 titled 'Pipelined Hybrid Noise-Shaping Analog-To-Digital Converter

Simplified Explanation

The abstract describes a system and method for implementing an analog-to-digital converter (ADC) with improved accuracy and noise cancellation capabilities.

  • The ADC consists of a first-stage quantizer, a second-stage quantizer, and a noise cancellation filter.
  • The first-stage quantizer takes in an analog input signal and generates a digital output signal, as well as a residual signal based on the input and output signals.
  • The second-stage quantizer receives the residual signal, determines the first-stage quantization error, digitizes it, and generates a second-stage digital output signal.
  • The noise cancellation filter takes both the first-stage and second-stage digital output signals and produces a noise-cancellation output signal that reduces the first-stage quantization error.

Potential applications of this technology:

  • High-precision measurement devices that require accurate conversion of analog signals to digital format.
  • Audio and video recording equipment that needs to capture and digitize analog signals with minimal noise and distortion.
  • Communication systems that rely on ADCs for converting analog signals to digital for transmission and processing.

Problems solved by this technology:

  • Improved accuracy in analog-to-digital conversion by reducing quantization errors introduced at each stage of the conversion process.
  • Enhanced noise cancellation capabilities to minimize the impact of quantization errors on the final digital output signal.

Benefits of this technology:

  • Higher accuracy and precision in converting analog signals to digital format.
  • Reduced noise and distortion in the digitized signals.
  • Improved signal-to-noise ratio, leading to better overall performance in various applications.


Original Abstract Submitted

Systems and methods are provided for implementing an analog-to-digital converter. In some embodiments, the analog-to-digital converter comprises a first-stage quantizer, a second-stage quantizer, and a noise cancellation filter. The first-stage quantizer is configured to receive an analog input signal and generate a first-stage digital output signal based on the analog input signal and a residual signal based on the first-stage digital output signal and the analog input signal. The second-stage quantizer is configured to receive the residual signal, to determine a first-stage quantization error based on the residual signal, to digitize the first-stage quantization error, and to generate a second-stage digital output signal based on the first-stage quantization error. The noise cancellation filter is configured to receive the first-stage digital output signal and the second-stage digital output signal and to generate a noise-cancellation output signal comprising a quantization error component less that the first-stage quantization error.
