Analog Electronics

Passive circuits 43

are summarized in Appendix 4. Here I have shown

for each circuit the circle diagram (vector diagram

as a function of frequency), the pole-zero dia-

grams for F(s) in plan and isometric view, and the

Bode plot, all together for comparison. I have not

seen this done in any other book, but I think you

will find it helpful. We will in any case be meeting

more pole-zero plots, circle diagrams etc. in later

chapters. But in the meantime, let's look at some

active devices - transistors, opamps and the like,

including those buffer amplifiers of which we have

already made use.
