Conclusion
In this chapter, the structured design of the frequency performance of a negative-feedback amplifier is discussed. It consists of two steps: first the LP product, which is a measure of the maximum attainable bandwidth, must be made high enough. This requires the identification of the group of dominant poles. Second, after realizing a sufficient LP product, the poles have to be placed to end up with the required relative frequency behavior, for instance Butterworth behavior.
The frequency compensation is done using the relevant part of the small-signal models only. Four types of frequency compensation techniques have been discussed and their influence on the LP product was investigated. The order of preference is:
-
• phantom zeros
-
• pole splitting
-
• pole-zero cancelation
-
• resistive broadbanding.
Finally, it was shown how current followers could validate the use of simple models in the process of frequency compensation.
