Bell Labs filed a patent in 1941 and many consider the first practical op amp to be the vacuum tube K2-W invented in 1952 by George Instruments invented the integrated circuit in 1958 which paved the way for Bob Widlarat Fairchild inventing the uA702 solid state monolithic op amp in 1963. -But it wasn t until the uA741, released in 1968, that op amps became relatively inexpensive and started on the road to ubiquity.

Key idea: add two quantities with opposite temperature coefficient with proper weightingÆthe resultant quantity exhibits zero temperature coefficient. Eg: V1 and V2 have opposite temperature dependence, choose the coefficients c1 and c2 in such a way that: Thus, the reference voltage V
