CHAPTER 8Signal Source Design

Signal sources generate some kind of signal like a sine wave or square wave. Such signal sources are called oscillators, multivibrators, clocks, timers, or frequency synthesizers. Some of these circuits are available as ICs you can use as needed. Others use an IC that requires external components. Some calculations are usually involved. Then there are the circuits you need to design from scratch.

Oscillator design is particularly challenging, as one example in this chapter will illustrate. In many design projects, you can solve the need of a signal source by simply adopting one of the popular circuits summarized in this chapter. No design is needed. Just acquire the ICs and add the external components that set the ...
