Current-feedback operational amplifier - The current feedback operational amplifier or CFB op-amp is a type of electronic amplifier whose inverting input is sensitive to current, rather than to voltage as in a conventional voltage-feedback (VFB) operational amplifier. The CFB op-amp was invented by David Nelson at Comlinear Corporation, and first sold in 1982 as a hybrid amplifier, the CLC103.

Operational amplifier - An operational amplifier or op-amp is a very high-gain amplifier which has two inputs, one inverting (âˆ’) and one non-inverting (+). The output voltage is the difference between the + and âˆ’ inputs, multiplied by the open-loop gain:

Set Theory: An Introduction to Independence Proofs - Set Theory: An Introduction to Independence Proofs is an important textbook and reference work in set theory by Kenneth Kunen. It starts from basic notions, including the ZFC axioms, and quickly develops combinatorial notions such as trees, Suslin's problem, â—Š, and Martin's axiom.

Introduction to Automata Theory, Languages, and Computation - Introduction to Automata Theory, Languages, and Computation also known as the Cinderella Book is an influential computer science textbook by Hopcroft and Ullman on the theory of computation. The first edition was published in 1979, the second edition in November 2000.
