Introduction to the Design of Transconductor-Capacitor Filters is a didactic presentation of a new and fast developing field. Transconductor-capacitor (gm-C) filters are emerging as the technique of choice for highfrequency analog integrated-circuit filtering in the range 1-100 MHz, in both CMOS and bipolar technologies. The primary objective of this book is to present this technique in a way which may be understood by students and practicing engineers entering this new field. The different topics are explained using detailed developed examples: biquad, gyrator and state-variable filters, bipolar and CMOS transconductors, and integrators, concluding with a completed design and SPICE simulation at the transistor level of a high-order filter. This book enables the researcher, who has been given a set of basic filter specifications, to choose a filter topology, design the transconductor and perform SPICE simulations at the transistor level of the complete filter to verify its design. The professional will also be able to access the more advanced literature on gm-C filters published in professional journals and understand what their authors are talking about, so that they can profit from other's experience. As such, readers will enrich their knowledge and find solutions to the problems that surely will be encountered during the practical design of a filter. This book serves as an excellent reference for researchers and design engineers, and is suitable for use as the textbook for advanced courses on the subject.
