A Use of Double Integration in Sigma Delta Modulation
Sigma delta modulation is viewed as a technique that employs integration and feedback to move quantization noise out of baseband. This technique may he iterated by placing feedback loop around feedback loop, but when three or more loops are used the circuit can latch into undesirable overloading modes. In the desired mode, a simple linear theory gives a good description of the modulation even when the quantization has only two levels. A modulator that employs double integration and twolevel quantization is easy to implement and is tolerant of parameter variation. At sampling rates of 1 MHz it provides resolution equivalent to 16 bit PCM for voiceband signals. Digital filters that are suitable for converting the modulation to PCM are also described.

The Structure of Quantization Noise from SigmaDelta Modulation
When the sampling rate of a sigmadelta modulator far exceeds the frequencies of the input signal. its modulation noise is highly correlated with the amplitude of the input. We derive simple algebraic expressions for this noise and its spectrum in terms of the input amplitude. The results agree with measurements taken on a breadboard circuit. This work can be useful for designing oversarnpled analog to digital converters that use sigmadelta modulation for the primary conversion.

Fully Controlled ThreePhase Bridge Converters
This chapter discusses the operation of a three‐phase fully controlled bridge converter. It is shown that by suitable control, this device can be used to achieve either a three‐phase controllable voltage source or a three‐phase controllable current source. The chapter presents a refinement of six‐step operation. In particular, one of several pulse‐width modulation (PWM) control strategies that allows the amplitude of the fundamental component of the voltage to be readily controlled is discussed. Six‐step modulation, extended sine‐triangle modulation, and space‐vector modulation are all voltage‐source modulation schemes. The chapter explains usage of these schemes to develop an open‐loop voltage‐regulated converter. Hysteresis modulation and delta modulation are both current source‐based schemes. These are used as the basis of developing an open‐loop current‐regulated converter. Finally, the chapter focuses on closed‐loop methods of regulating q‐ and d‐axis voltages and currents.

Multirate Filter Designs Using Comb Filters
Decimation is an important component of oversampled analogtodlgital conversion. It transforms the digitally modulated signal from short words occurring at high sampling rate to longer words at the Nyquist rate. Here we are concerned with the initial stage of decimation, where the word rate decreases to about four times the Nyquist rate. We show that digital filters comprising cascades of integrateanddump functions can match the structure of the noise from sigma delta modulation to provide decimation with negligible loss of signaltonoise ratio. Explicit formulas evaluate particular tradeoffs between modulation rate, signaltonoise ratio, length of digital words, and complexity of the modulating and decimating functions.

A Novel Architecture Design for VLSI Implementation of an FIR Decimation Filter
A novel architecture design of a one stage FIR filter for decimation is described. It performs the decimation of a 1bit code at 1024KHz of double integration Sigma Delta modulation output to PCM at 16KHz. This architecture is designed in such a way that it needs only a simple control structure suitable for VLSI implementation. We devised an algorithm for generating the coefficients of the filter with a minimum of required hardware. It does not require storing the coefficients in a ROM and continuously reading it to calculate the convolution. The accumulators needed to perform the direct convolution are arranged in a way that simplifies and minimizes the hardware required for the filter implementation. The filter response is Sinc3(f) which provides sufficient attenuation for modulation generated by means of double integration. The implementation of this filter requires the generation of the coefficients and the performance of the convolution. Three coefficients are needed with every input to obtain the output sequence. The major feature of this architecture is the use of an efficient algorithm to obtain the coefficients thereby reducing the area and power consumption. It is very suitable for VLSI implementation in CMOS technology.

An Approach to the Implementation of Digital Filters
An approach to the implementation of digital filters is presented that employs a small set of relatively simple digital circuits in a highly regular and modular configuration, well suited to LSI construction. Using parallel processing and serial, two'scomplement arithmetic, the required arithmetic circuits (adders and multipliers ) are quite simple, as are the remaining circuits, which consist of shift registers for delay and small readonly memories for coefficient storage. The arithmetic circuits are readily multiplexed to process multiple data inputs or to effect multiple, but different, filters (or both), thus providing for efficient hardware utilization. Up to 100 filter sections can be multiplexed in audiofrequency applications using presently available digital circuits in the mediumspeed range. The filters are also easily modified to realize a wide range of filter forms, transfer functions, multiplexing schemes, and roundoff noise levels by changing only the contents of the readonly memory and/or the timing signals and the length of the shiftregister delays. A simple analogtodigital converter, which uses delta modulation as an intermediate encoding process is also presented for audiofrequency applications.

A SecondOrder HighResolution Incremental A/D Converter with Offset and Charge Injection Compensation
Sigmadelta modulation, associated with oversampling and noise shaping, is a wellknown technique used in highaccuracy A/D converters. Such converters, required in telecommunications applications, are characterized by ac perfonnance such as signaltonoise ratio. Moreover, they are mainly dedicated to applications which can tolerate offset and gain errors. On the other hand, measurement and instrumentation applications require absolute accuracy, e.g., offset and gain errors cannot be tolerated. These applications are characterized by dc perfonnance such as differential and integral nonlinearides, offset and gain errors, and they often require high resolution. The secondorder incremental A/D converter, which makes use of sigmadelta modulation associated with a simple digital filter, is capable of achieving such requirements. Experimental results, obtained of circuits fabricated in a SACMOS 3Â¿m technology, indicate that 15bit absolute accuracy is easily achievable, even with a low reference voltage.

Constraints Analysis for Oversampling AtoD Converter Structures on VLSl Implementation
Requirements, applied to analog components and characteristics for oversampling AtoD converter structures with second order loop transfer function, were analyzed through numerical and mathematical analyses. The results suggest that a first order predictive encoder, with first order noise shaping, is best suited to high resolution future VLSl implementation. It is most difficult to achieve a theoretical second order Â¿Â¿ modulation signal tonoise ratio, because of the amplifier performance requirements. The operational amplifier gain should only be greater than kR/n, as long as the amplifier response is linear, where R is the oversampling ratio, Â¿ is the angular stop band frequency and k is a. parameter depending on structures and integrator circuit configuration, if a switched capacitor integrator is employed in a noise shaping technology. A second order delta modulation coder does not seem to be applicable to a precision converter, but to a high speed converter instead.
