Mixed-signal and DSP Design Techniques

Rating:
Summary: Untangling mixed signals
Review: This book is based on a set of Seminar Notes that had previously been available only from Analog Devices. It's refreshing to see this new edition, from Newnes, edited by Walt Kester, with its updated information-particularly in the digital signal-processing (DSP) area.

Packed with design information from engineers with years of experience, and backed up by many references, this volume covers the details of both analog and digital signal-processing (DSP), as well as the requisite analog-digital interfacing. Perhaps the best way to review it is to let the chapter headings speak for themselves:
Introduction-about real-world signals and signal processing, with a practical example

Sampled data systems: Discrete time sampling, static transfer functions and dc errors, ac errors in data converters, D/A converter dynamic performance

A/D converters for DSP applications: Successive-approximation, sigma-delta, flash, subranging (pipelined), bit-per-stage

D/A converters for DSP applications: DAC structures, low-distortion architectures, logic, interpolating, sigma-delta, direct digital synthesis (DDS)

Fast Fourier transform (FFT): Discrete Fourier transform (DFT), fast Fourier transform, FFT hardware and benchmarks, DSP requirements for real-time FFT, spectral leakage and windowing

Digital filters: Finite impulse response (FIR), implementations in DSPs, circular buffering, FIR designing, infinite impulse response (IIR), design techniques for IIR, multirate, adaptive

DSP hardware: Microcontrollers, microprocessors, and DSPs; DSP requirements; ADSP-21xx 16-bit fixed-point core; fixed-point vs. floating-point; SHARC DSPs; ADSP-2116x single-instruction, multiple-data (SIMD) core; TigerSHARC, static superscalar; DSP evaluation and CROSSCORE™ tools

Interfacing to DSPs: Parallel interfacing, reading from memory-mapped peripheral ADCs; writing to memory-mapped DACs; serial interfacing; I/O ports, analog front ends, and codecs; high-speed interfacing; DSP system interface

DSP applications: High performance modems for POTS; RAS modems; ADSL; digital cellular; GSM, SoftFone, Othello; analog cellular base stations; digital base stations; motor control, codecs and DSPs in voiceband and audio; sigma-delta ADC with programmable digital filter; applications summary

Hardware design techniques: Low-voltage interfaces, grounding in mixed-signal systems, digital isolation techniques, power-supply noise reduction and filtering, dealing with high-speed logic.

This is a book by a set of experts and edited by an experienced practitioner--Walt Kester, a Staff Applications Engineer at Analog Devices. He has designed, developed, and given applications support for high-speed ADCs, DACs, sample-hold amplifiers, op amps, and multiplexers--and it shows, as evidenced by his authoritative, practical, down-to-earth approach.
