Abstrac
The effects of pole-zero pairs (doublets) on the frequency
response and settling time of operational amplifiers are
explored using analytical techniques and computer simulation. It
is shown that doublets which produce only minor changes in circuit
frequency response can produce major changes in settling time. The
importance of doublet spacing and frequency are examined. It is
shown that settling time always improves as doublet spacing is
reduced whereas the effect of. doublet frequency is different for
0.1 and 0.01 percent error bands. Finally it is shown that simple
analytical formulas can be used to estimate the influence of frequency
doublets on amplifier settling time. |
