A 13-Bit, 1.4-MS/s Sigma–Delta Modulator for RF Baseband Channel Applications
نویسندگان
چکیده
A 13-bit, 1.4-MS/s, sixth-order cascaded sigma–delta modulator oversampling at 16 X is implemented in a 0.72 m complementary metal–oxide–semiconductor process for use in the baseband path of a radio-frequency receiver. The modulator achieves 77 dB of dynamic range and dissipates 81 mW from a 3.3 V supply. It is characterized for the blocking and intermodulation requirements of a cordless telephone application.

A 24-Bit, 8.1-MS/s D/A Converter for Audio Baseband Channel Applications
This paper study the high-level modelling and design of delta-sigma ( ) noise shapers for audio Digital-to-Analog Converter (DAC) so as to eliminate the in-band Signal-to-NoiseRatio (SNR) degradation that accompany one channel mismatch in audio signal. The converter combines a cascaded digital signal interpolation, a noise-shaping single loop delta-sigma modulator with a 5-bit quantizer resolut...
متن کاملBaseband Filter and Σ∆ Converter for Wideband RF receiver
ABSTRACT This paper describes a fully-differential anti-alias filter (AAF) and analog-to-digital converter (ADC) for baseband processing of a wideband RF signal. The AAF is a third order elliptic low-pass filter. The ADC is a 2-2 cascade sigma-delta architecture with a single-bit quantizer in the first stage and a 13-level quantizer in the second stage. The system converts a 2.5 MHz input signa...

متن کاملDesign of Wideband Continuous-Time ΔΣ ADCs Using Two-Step Quantizers
Continuous-time delta sigma (CT-4Σ) ADCs are established as the data conversion architecture of choice for the next-generation wireless applications. Several efforts have been made to simultaneously improve the bandwidth and dynamic range of 4Σ ADCs. We proposed using two-step quantizer in a single-loop CT-4Σ modulator to achieve higher conversion bandwidth. This paper presents a tutorial for e...
