Introduction to Op Amp Basics
Within Chapter 1, discussions are focused on the basic aspects of op amps. After a brief introductory section, this begins with the fundamental topology differences between the two broadest classes of op amps, those using voltage feedback and current feedback. These two amplifier types are distinguished more by the nature of their internal circuit topologies than anything else. The voltage feedback op amp topology is the classic structure, having been used since the earliest vacuum tube based op amps of the 1940s and 1950s, through the first IC versions of the 1960s, and includes most op amp models produced today. The more recent IC variation of the current feedback amplifier ...
