his book presents a collection of analog electronic circuits based on the op-amp, supported by a wealth of practical detail which will enable the reader to speedily select, build and test a desired circuit. The book is primarily intended to be a practical reference volume rather than a teaching text. Readers will discover an extensive and invaluable source of functional and established analog circuits, from integrators and differentiators to logarithmic amplifiers, from filters to instrumentation amplifiers. The circuits are grouped according to function, and the approach is to build up slowly from the basic textbook examples towards a series of practical, workable circuits. Students who need to build and test particular types of analog circuitry as part of an assignment or project based activities will find this book invaluable. Professional engineers will also find the book useful for design and development work. The coverage is extensive and up-to-date, and provides a wealth of technical advice.
