An anti-aliasing multi-rate ΣΔ modulator
2009 Edition, May 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

By splitting the input sampling capacitor of a SigmaDelta modulator into several time-interleaved branches, FIR filtering can be incorporated into the signal transfer function. Doing so imposes little or no overhead in the design of the opamps. Simulations of a 3rd-order modulator...

20.7 A 72.6dB-SNDR 100MHz-BW 16.36mW CTDSM with Preliminary Sampling and Quantization Scheme in Backend Subranging QTZ
2019 Edition, February 1, 2019 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Driven by great demands for high data transfer rates in mobile communications, ADCs require wide bandwidths with low noise density and power consumption. The continuous-time $\Delta\Sigma $ modulator (CTDSM) is a suitable candidate for such applications as it has a simple slew...

A 1.2-V 77-dB 7.5-MHz Continuous-Time/Discrete-Time Cascaded ΣΔ Modulator
2007 Edition, June 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A hybrid ΣΔ modulator combines the anti-aliasing filtering and high sampling rate advantages of a continuous-time first stage with a low-power discrete-time second stage. A 0.18-μm CMOS experimental prototype samples signals at 240 MHz and achieves 77 dB of...

20.6 An 80MHz-BW 31.9fJ/conv-step Filtering ΔΣ ADC with a Built-In DAC-Segmentation/ELD-Compensation 6b 960MS/s SAR-Quantizer in 28nm LP for 802.11ax Applications
2019 Edition, February 1, 2019 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The demand for modern portable smart devices is growing at an unprecedented rate, which speeds up the development of the next-generation wireless-LAN (WLAN) standard. To improve spectrum efficiency and serve more users in crowded areas while increasing maximum throughput, 802.11ax...

A 50MHZ-BW continuous-time ΔΣ ADC with dynamic error correction achieving 79.8dB SNDR and 95.2dB SFDR
2018 Edition, February 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Continuous-time ΔΣ modulators (CTDSMs) are widely used in cellular handsets due to their power efficiency and inherent anti-aliasing characteristics. To achieve demanding cellular bandwidth requirements while maintaining good power efficiency, multi-bit feedback is...

A double-sampled hybrid CT/DT SMASH ΣΔ modulator for wideband applications
2009 Edition, December 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a novel hybrid continuous-time (CT) and discrete-time (DT) sturdy multi-stage noise shaping (SMASH) ΣΔ modulator architecture. The double-sampling technique is employed in the DT second stage modulator to reduce the power consumption of the overall...

A new interpolation technique for TI ΣΔ A/D converters
2010 Edition, May 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Time interleaved sigma-delta converter is a potential candidate for multi-mode wideband analog to digital (A/D) converters dedicated for multistandard receivers. However, the interpolation by zeros recquired to compress the useful signal bandwidth at the input of the sigma-delta...
