Abstract
Provided are embodiments that include a circuit configured to operate in a disabled mode error reduction for high-voltage bilateral operational amplifier current source. The circuit includes an operational amplifier, and a switching circuit coupled to the operation amplifier, wherein the switching circuit is operable in a normal mode and a disabled mode, wherein the disabled mode reduces error current at the output of the operational amplifier. Also provided are embodiments for a method for operating a circuit in a disabled mode for error reduction.
