By preface - During its first decade as a transistor manufacturer, Texas Instruments Incorporated has received many thousands of requests for assistance with circuit design problems. TI has responded to these queries by means of both personal communications and application bulletins having limited circulation. The pattern of recurring inquiries which has emerged suggested both the need for this book and its content.“Transistor Circuit Design” was compiled for the practicing circuit design engineer. It offers solutions to a wide range of basic engineering problems. A few of the discussions are addressed to the tyro; most require a considerable degree of engineering sophistication; all have proved to be of interest to our correspondentsOne volume cannot encompass discussions in depth of all design problems.Accordingly, this edition is the first of a series-subject matter Will be selected and revised in response to recommendations from our readers and as required by advances in the art. Although engineers throughout the Semiconductor-Components division have contributed to this volume, TI’s Transistor Applications branch is responsible for its final form and will welcome suggestions and inquiries.Information contained in this book is believed to be accurate and reliable.However, responsibility is assumed neither for its use nor for any infringement of patents or rights of others which may result from its use.
