A continuous-time reduced-sample-rate ΔΣ-pipeline ADC for broadband wireless applications
2007 Edition, August 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a continuous-time 2-0 cascade delta-sigma modulator. The first stage of the modulator is a second-order continuous-time modulator with low-distortion structure. The second stage is a pipeline ADC with reduced...

Blocker tolerant wideband continuous time sigma-delta modulator for wireless applications
2014 Edition, August 1, 2014 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A continuous-time low-pass ΔΣ ADC equipped with design techniques to provide robustness against saturation due to blockers is presented. An integrated low pass blocker filter that reduces the most critical adjacent/alternate channel blockers by 7/11 dB,...

A 4GHz CT ΔΣ ADC with 70dB DR and −74dBFS THD in 125MHz BW
2011 Edition, February 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, a high-speed continuous-time (CT) ΔΣ ADC topology is proposed that absorbs the pole normally caused by the quantizer's input capacitance, while a local feedback loop compensates for the quantizer's excess delay. These measures allow...

A low-power 10MHz bandwidth continuous-time ΣΔ ADC with Gm-C filter
2014 Edition, August 1, 2014 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we design a high-speed and wide-bandwidth continuous-time sigma-delta modulator (CT-SDM). We emphasize the design of low power wide-bandwidth (10MHz) CT-SDM for WLAN Std. 802.11b receiver. In the application of wireless receiver,...

Systematic synthesis of cascaded continuous-time ΔΣ ADCs for wideband data conversion
2013 Edition, August 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Continuous-time delta sigma (CT-ΔΣ ) ADCs are gaining wider adoption in data conversion systems primarily aided by their robustness to mismatch in nano-scale CMOS technologies and inherent anti-alias filtering. In past, several techniques have been employed to achieve...

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
