An old but interesting app note (PDF!) from Linear on high speed amplifier techniques:
Most monolithic amplifiers have been relatively slow
devices. Wideband operation has been the province o
discrete and hybrid technologies. Some fast monolithic
amplifiers have been available, but the exotic and expensive
processing required has inflated costs, precluding
widespread acceptance. Additionally, many of the previous
monolithic designs were incapable of high precision and
prone to oscillation or untoward dynamics, making them
unattractive.
Recent processing and design advances have made inex-
pensive, precision wideband amplifiers practical. Figure 1
lists some amplifiers, along with a summary of their
characteristics. Reviewing this information reveals ex-
traordinarily wideband devices, with surprisingly good DC
characteristics. All of these amplifiers utilize standard op
amp architecture, except the LT1223 and LT1228, which
are so-called current mode feedback types (see Appendix
H, “About Current Mode Feedback”). It is clear that the raw
speed capabilities of these devices, combined with their
inherent flexibility as op amps, permit a wide range o
applications. What is required of the user is a familiarity
with the devices and respect for the requirements of high
speed circuitry.
Another brilliant Jim Williams app-note. His collective works should be on any EE’s list.
