Figure 1a shows the classic implementation of an integrator. The circuit has two properties that may be undesirable in same applications: It necessarily inverts, and it requires a split-supply or ...

(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) In the first article of this series, “Operational Amplifier–The Basic Building Block” ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

As an applications engineer for a company making configurable analog products, I occasionally get asked to provide a design to integrate a signal before digitizing it. In many cases, the people doing ...
