A multi-carrier base station receiver using a delta-sigma oversampling A/D converter

2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2002

This paper presents the results of work at TRW in developing a multi-carrier receiver for cellular base station applications. Replacing existing single carrier receivers with a multi-carrier receiver has the potential to significantly increase the capacity of existing mobile phone networks and reduce the cost per carrier. Implementation of a multi-carrier receiver has been limited by the large dynamic range ...


A Nyquist-rate pipelined oversampling A/D converter

1999 IEEE International Solid-State Circuits Conference. Digest of Technical Papers. ISSCC. First Edition (Cat. No.99CH36278), 1999

Oversampling and noise-shaping techniques, such as /spl Sigma//spl Delta/ modulation, have an inherent tradeoff between accuracy and speed, whereby resolution in amplitude is at the expense of resolution in time. Because their internal circuits must operate over many clock cycles to produce a single result, they have limited data rates and power dissipation is a concern. Much attention has been ...


High-order single-stage single-bit oversampling A/D converter stabilized with local feedback loops

Proceedings of 36th Midwest Symposium on Circuits and Systems, 1993

A new method for the stabilization of high-order (>2) single-stage single-bit oversampling A/D converters is proposed. In this approach, the stability of the modulator is achieved by preventing any unbounded increase in the internal node-voltages through the insertion of local feedback signals inside the modulator loop. Local feedback loops prevent individual integrators from saturating and keep the output voltages within ...

  • A multi-carrier base station receiver using a delta-sigma oversampling A/D converter

    This paper presents the results of work at TRW in developing a multi-carrier receiver for cellular base station applications. Replacing existing single carrier receivers with a multi-carrier receiver has the potential to significantly increase the capacity of existing mobile phone networks and reduce the cost per carrier. Implementation of a multi-carrier receiver has been limited by the large dynamic range requirements for GSM/EDGE and WCDMA standards, with the GSM 900 MHz band presenting the greatest challenge. TRW is leveraging several proprietary technologies that enable and facilitate this development, including the latest product in a series of high performance analog-to-digital converters (ADCs). The stressing requirements for very high dynamic range (up to 108 dB SNR), wide bandwidth, and high linearity are met by employing a delta-sigma ADC that redefines the state-of-the-art. TRW's world-class InP process is used to fabricate devices capable of the high level of oversampling needed to satisfy the demanding performance values. We describe the receiver architecture and present preliminary test results from our first engineering model, demonstrating the practicality of a multi-carrier receiver for cellular base stations.

  • A Nyquist-rate pipelined oversampling A/D converter

    Oversampling and noise-shaping techniques, such as /spl Sigma//spl Delta/ modulation, have an inherent tradeoff between accuracy and speed, whereby resolution in amplitude is at the expense of resolution in time. Because their internal circuits must operate over many clock cycles to produce a single result, they have limited data rates and power dissipation is a concern. Much attention has been focused on improving the speed and power of /spl Sigma//spl Delta/ analog-to-digital converters (ADCs) by use of higher-order modulators, multi-bit feedback, and multi-bit architectures with single-bit feedback. However, data rates remain limited to less than a few MHz and are not easily extended. A pipelined oversampling architecture circumvents this speed- resolution tradeoff by performing spatial, rather than temporal, oversampling. It combines the high resolution of /spl Sigma//spl delta/ techniques with the high speed of pipelined converters so that both of these attributes are simultaneously achievable.

  • High-order single-stage single-bit oversampling A/D converter stabilized with local feedback loops

    A new method for the stabilization of high-order (>2) single-stage single-bit oversampling A/D converters is proposed. In this approach, the stability of the modulator is achieved by preventing any unbounded increase in the internal node-voltages through the insertion of local feedback signals inside the modulator loop. Local feedback loops prevent individual integrators from saturating and keep the output voltages within the proper bounds. The error caused by the local feedback signals is cancelled by feeding these signals through a digital correction path. Since the frequency of overloading can be made very low by proper design, the effect of imperfect cancellation due to mismatches in the two signal paths caused by the modulator nonidealities is quite small. Hence, compared to the MASH architectures, the proposed approach achieves stability with lower sensitivity to finite op amp gain, an advantage in the modern low power/low voltage technologies.<<ETX>>

  • Superconducting delta-sigma oversampling A/D converter

    A superconducting delta-sigma analog-to-digital (A/D) converter is presented. The converter uses a low-pass filter instead of the integrator found in the usual delta-sigma architecture. The converter is analyzed by a behavior-level simulation package as well as the circuit simulator JSIM. Its performance is compared to that of the standard first-order delta-sigma converter. The simulation shows that this converter can achieve a 70-dB signal-to-noise ratio (S/(N+D)) with an oversampling ratio of 128. This corresponds to an 11-b resolution. The signal bandwidth is 4 MHz if the sampling rate is 1 GHz.<<ETX>>

  • A Nyquist-rate pipelined oversampling A/D converter

    A pipelined /spl Delta/-/spl Sigma/ analog-to-digital-converter architecture is described that incorporates the high speed of pipelined converters and the high resolution of oversampling quantization. A prototype, containing both modulation and decimation circuits on a single chip, is implemented using a 1.2-/spl mu/m commercial CMOS process. It uses charge-coupled-device elements to perform pipelined analog operations. It exhibits a maximum data rate of 18 MHz, a signal-to-noise ratio of 74 dB, spurious-free dynamic range of 78 dB, differential nonlinearity of <0.15 LSB at 13 bits, and power dissipation of 324 mW.

  • The effects of switching noise on an oversampling A/D converter

    This paper presents the results of an experimental study of the effects of switching noise in a high-resolution oversampling /spl Sigma//spl Delta/ modulator. An experimental test circuit emulates the embedding of such a modulator in the same substrate as a large amount of active digital circuitry. The modulator is a third-order cascade comprising a second-order /spl Sigma//spl Delta/ stage followed by a first-order stage, both employing 1 b quantisation. A 1 /spl mu/m CMOS implementation of this design provides a dynamic range of more than 100 dB at digital audio bandwidths.
