A new cascade ΣΔ modulator for low-voltage wideband applications
نویسنده
چکیده
This letter presents a new cascade ΣΔ modulator architecture with unity signal transfer function that avoids the need of digital filtering in the error cancellation logic. The combination of these two aspects make it highly tolerant to noise leakages, very robust to non-linearities of the circuitry and especially suited for low-voltage implementations at low oversampling. Behavioral simulations are presented that demonstrate the higher efficiency of the proposed topology compared to existing cascades intended for wideband applications.

Resonation-based cascade ΣΔ modulator for broadband low-voltage A/D conversion
This letter presents a novel cascade ΣΔ modulator architecture that employs inter-stage resonation to increase its effective resolution compared to traditional cascades while presenting very relaxed output swing requirements and, subsequently, high robustness to non-linearities of the amplifiers. In addition, the use of loop filters based on Forward-Euler integrators, instead of Backward-Euler ...

A wideband 2-1-1 cascaded ΣΔ modulator with a single-bit quantizer in the two first stages and a 4-bit quantizer in the final stage is developed. To reduce sensitivity of digital-to-analog converter (DAC) nonlinearities in the feedback of the last stage, dynamic element matching (DEM) is introduced. This paper presents two modelling approaches: The first is MATLAB description and the second is ...

A continuous-time (CT) ΣΔ modulator for sensing and direct analog-to-digital conversion of nA-range (subthreshold) currents is presented in this work. The presented modulator uses a subthreshold technique based on subthreshold source-coupled logic cells to efficiently convert subthreshold current to digital code without performing current-to-voltage conversion. As a benefit of this technique, t...
