With growing consumer demand for portability and miniaturization in electronics, design engineers must concentrate on many additional aspects in their core design. The plethora of components that must be considered requires that engineers have a concise understanding of each aspect of the design process in order to prevent bug-laden prototypes.

Electronic Circuit Design allows engineers to understand the total design process and develop prototypes which require little to no debugging before release. It providesstep-by-step instruction featuring modern components, such as analog and mixed signal blocks, in each chapter. The book details every aspect of the design process from conceptualization and specification to final implementation and release. The text also demonstrates how to utilize device data sheet information and associated application notes to design an electronic system.

The hybrid nature of electronic system design poses a great challenge to engineers. This book equips electronics designers with the practical knowledge and tools needed to develop problem free prototypes that are ready for release.

1.1 Introduction

Circuit design can be considered an art based on the fundamental concepts we learn in electrical and electronic engineering. With the unprecedented advancement of semiconductors, today a designer has many choices of components. Although keeping track of all the new integrated circuits (ICs) appearing on the market is a difficult task, it may be particularly useful if design challenges include miniaturization of the overall product. Passive components such as resistors, capacitors, inductors, and transformers need to be mixed effectively and optimally with semiconductor components in building a particular circuit. In this exercise of “design and development,” the designer needs to work with the delicate balance between the real or the analog world, where signals can take any value within a given range, and the digital world, where we make use of processors, memories, and other peripheral devices to accurately process information. To summarize the need for the delicate balance required, it may be appropriate to cite Jim Williams, a well-known linear circuit designer: “Wonderful things are going on in the forgotten land between ONE and ZERO. This is real electronics.” Within the past quarter century, a new domain of semiconductors has appeared that links the analog and digital worlds. That is the world of mixed signal electronics, where analog-to-digital conversion, and vice versa, occurs. In this book, emphasis is placed on the analog world of electronics together with the mixed signal domain of design.
