CHAPTER 1

Introduction to Micropower/Battery Design

This chapter is devoted to basic problems involved in the design of micropower/battery circuits. Specific problems for the design of single-cell battery circuits are covered in Chapter 4. In this chapter, we are concerned with the overall problems and the corresponding solutions for micropower/battery equipment. These circuits include single-cell and multicell battery-operated devices, as well as any circuit that requires low-power consumption.

1.1 Basic Approaches to Low-Power Circuit Design

There are many basic approaches to limiting power consumption. First, and most obvious, is to select low-power components, particularly low-power ICs. Both low-quiescent and low-operating currents must ...
