CMOS Current Amplifiers presents design strategies for high performance current amplifiers based on CMOS technology. After an introduction to various architectures of operational amplifiers, the operating principles of the current amplifier are outlined. This book provides the reader with simple and compact design equations for use in a pencil and paper design and the following simulation step. Chapter 1 introduces the general aspects of current amplifiers. After a preliminary classification of operational amplifiers, ideal blocks and models are discussed for different architectures and a first high-level comparison is made between traditional amplifiers and current amplifiers. Analysis and examples of basic circuits, as well as signal processing applications involving current amplifiers, are also given. Non-idealities and second- order effects causing limitations in performance are then discussed and evaluated. Chapter 2 focuses on low-drive current amplifiers. Several design examples for current conveyors and class A current amplifiers are discussed in detail and design equations are presented for the main performance parameters, which allows a good trade-off between requirements. High-performance solutions for high bandwidth and low voltage capability are also considered, and, finally, current comparators with progressively enhanced performance are reported and analyzed critically. Chapter 3 deals with current amplifiers for off-chip loads. Several class AB current-mode output stages are discussed and design strategies which improve performance are presented. A detailed analysis of non-ideal effect is carried out with particular emphasis on linearity. Design examples are given and circuit arrangements for further developments are included. CMOS Current Amplifiers serves as an excellent reference for researchers and professionals of analog IC design, and may also be used as an advanced text on current amplifiers.

Within the framework of the human rights treaty system of the European Social Charter, the collective complaints procedure was created in 1995 as an optional quasi-jurisdictional monitoring mechanism specific for the protection of social rights. In recent years, the importance and use of this procedure has increased considerably, in the context of a number of serious economic and social crises which are impacting negatively on the effective enjoyment of social rights in Europe.The present monograph explores and clarifies the specific features of the collective complaints procedure, intended as a sui generis instrument for the protection of social rights in the light of its evolutive application by the European Committee of Social Rights (the monitoring body of the European Social Charter) and its real impact on the state and conditions of social rights in the European countries concerned.The analysis particularly dwells on the collective nature of the mechanism, and its implications from the standpoint of the admissibility of complaints, on the adversarial character of the procedure and on the particularities of the follow-up to findings of violation adopted by the European Committee of Social Rights (ECSR). The crucial issues concerning the legal value and effects of the ECSR's decisions on the merits of collective complaints, on the one hand, and the effectiveness of the collective complaints procedure as a means for the protection of social rights, on the other hand, are also addressed. Lastly, the book proposes some reflections on the supposed limitations on the effectiveness of a procedure which is conceived to deal not with individual situations of human rights violations but with violations characterized by elements of "e;collective importance"e; for many subjects.
