20150109158 | MULTI-STAGE NOISE SHAPING ANALOG-TO-DIGITAL CONVERTER - The present disclosure describes an improved multi-stage noise shaping (MASH) analog-to-digital converter (ADC) for converting an analog input signal to a digital output signal. In particular, a full delta-sigma (ΔΣ) modulator is provided at the front-end of the MASH ADC, and another full ΔΣ modulator is provided at the back-end of the MASH ADC. The front-end ΔΣ modulator digitizes an analog input signal, and the back-end ΔΣ modulator digitizes an error between the output of the front-end ΔΣ modulator and the (original) analog input signal. In this configuration where the back-end modulator digitizes the error of the (full) front-end modulator, some design constraints of the front-end are relaxed. These design constraints include thermal noise, digital noise cancellation filter complexity (the quantization noise of the front-end is already shaped by the noise transfer function of the front-end), and/or non-linearity. | 04-23-2015 |
20150123828 | INTEGRATOR OUTPUT SWING REDUCTION - In one example implementation, the present disclosure provides a loop filter for use in a continuous-time sigma-delta analog-to-digital converter.

Specifically, using an inductor-capacitor (LC) lattice based delay element to enable high-performance CT pipeline ADC and CT delta-sigma (ΔΣ) ADC. The use of an LC lattice based delay element provides wide-band group delay for continuous-time signals with well-controlled impedance. This will be an essential circuit component to build a high-performance CT ADCs especially in architectures where the generation of a low-noise and low-distortion residual between the CT signal and its digitized version is needed. LC lattice based delay element enables noise-free, distortion-free wideband delay that is required for high speed continuous-time pipeline ADC and delta-sigma ADC. | 09-03-2015 |
