The effect of capacitances and inductances is so acute in high-speed digital circuits, for example, that our simple digital abstractions developed in Chapter 6 based on a static discipline become insufficient for signals that undergo transitions. Therefore, understanding the behavior of circuits containing capacitors and inductors is important. In particular, this chapter will augment our digital abstraction with the concept of delay to include the effects of capacitors and inductors. Looked at positively, because they can store energy, capacitors and inductors display the memory property, and offer signal-processing possibilities not available in circuits containing only resistors. Apply a square-wave voltage to a multi-resistor linear circuit, and all of the voltages and currents in the network will have the same square-wave shape. But include one capacitor in the circuit and very different waveforms will appear sections of exponentials, spikes, and sawtooth waves. Figure 10.1 shows an example of such waveforms for the two-inverter system of Figure 9.1 in Chapter 9. The linear analysis techniques already developed node equations, superposition, etc. are adequate for finding appropriate network equations to analyze these kinds of circuits. However, the formulations turn out to be differential equations rather than algebraic equations, so additional skills are needed to complete the analyses. vI vO t vI + - t + vO - . F I G U R E .
