DC-Coupled Single-Supply Op Amp Design Techniques
AC-coupled, single-supply op amp circuits are relatively easy to deal with, but not all applications can be AC coupled. Op amp circuits that must include DC gain have to take into account the DC gain applied to the reference as well and simultaneously apply the proper gain to both. The general solution to this problem is approached using simultaneous equations and lead to solutions in the four quadrants of a Cartesian coordinate graph.
