The area of analog integrated circuits is facing some serious challenges due to the ongoing trends towards low supply voltages, low power consumption and high-frequency operation. The situation is becoming even more complicated by the fact that many transfer functions have to be tunable or controllable. A promising approach to facing these challenges is given by the class of dynamic translinear circuits, which are, as a consequence, receiving increasing interest. Several different names are used in literature: log-domain, exponential state-space, current-mode companding, instantaneous companding, tanh-domain, sinh-domain, polynomial state-space, square-root domain and translinear filters. In fact, all these groups are (overlapping) subclasses of the overall class of dynamic translinear circuits. Research Perspectives on Dynamic Translinear and Log-Domain Circuits is a compilation of research findings in this growing field. It comprises ten contributions, coming from recognized `dynamic-translinear' researchers in Europe and North America. Research Perspectives on Dynamic Translinear and Log-Domain Circuits is an edited volume of original research.

Low-Voltage Low-Power Analog Integrated Circuits brings together in one place important contributions and state-of-the-art research results in this rapidly advancing area. Low-Voltage Low-Power Analog Integrated Circuits serves as an excellent reference, providing insight into some of the most important issues in the field.

Log-domain and translinear filters provide a competitive alternative to the challenges of ever increasing low-voltage, low-power and high frequency demands in the area of continuous-time filters. Since translinear filters are fundamentally large-signal linear, they are capable of realizing a large dynamic range in combination with excellent tunability characteristics. Large-signal linearity is achieved by exploiting the accurate exponential behavior of the bipolar transistor or the subthreshold MOS transistor. A generalization of the dynamic translinear principle exploiting the square law behavior of the MOS transistor is theoretically possible, but not practically relevant. Translinear and log-domain filters are based on the dynamic translinear principle, a generalization of the conventional (static) translinear principle. Besides their application for linear filters, dynamic translinear circuits can also be used for the realization of non-linear dynamic functions, such as oscillators, RMS-DC converters and phase-locked loops. Dynamic Translinear and Log-Domain Circuits: Analysis and Synthesis covers both the analysis and synthesis of translinear circuits. The theory is presented using one unifying framework for both static and dynamic translinear networks, which is based on a current-mode approach. General analysis methods are presented, including the large-signal and non-stationary analysis of noise. A well-structured synthesis method is described greatly enhancing the designability of log-domain and translinear circuits. Comparisons are made with respect to alternative analysis and synthesis methods presented in the literature. The theory is illustrated and verified by various examples and realizations. Dynamic Translinear and Log-Domain Circuits: Analysis and Synthesis is an excellent reference for researchers and circuit designers, and may be used as a text for advanced courses on the topic.

Demonstrates the development of a class-AB current-mode sample-and-hold circuit with an order of magnitude improvement in its figure of merit compared to other state-of-the-art designs. The concepts and design procedures of single-branch filters, follower-integrator-based lowpass filters, and modular transconductance reduction techniques for very low frequency filters are also presented.

This book helps circuit designers reduce errors introduced by the fundamental limitations and electromagnetic interference (EMI) in negative-feedback amplifiers. It details a systematic design approach for application specific negative-feedback amplifiers.

With a billion - soon to be two billion - cellular telephones in circulation, the next challenge is to make cellular radio functions adaptive to their environment. This book provides a comprehensive theoretical framework for optimizing performance, discussing joint optimization of Noise Figure and Input Intercept Point in receiver systems.

in pacemakers, where the wavelet transform provides a means to extremely reliable cardiac signal detection.In Ultra Low-Power Biomedical Signal Processing we present a novel method for implementing signal processing based on WT in an analog way.

This superb text provides a systematic way to support the system architect in this job. Therefore, an iterative system-level design approach is defined where iterations are based on fast and accurate estimations or predictions of area, performance and energy consumption.
