Abstract: In some electronic systems, a DC offset voltage at the inputs will contribute a significant error to the output. This is especially true in high gain configurations. An offset adjustment circuit can be added to "null" out the offset voltage, making high gain stages practical even with significant input offset voltages found in op amp circuits.

This is especially true in high gain configurations. An offset adjustment circuit can be added to "null" out the offset voltage, making high gain stages practical even with significant input offset voltages found in op amp circuits. Electronic Potentiometers (EPOTS) offer designers the opportunity to control a resistance via a digital interface and can be used in place of mechanical ……
