Abstract
A method and apparatus for customizing the gain of a closed loop operational amplifier during fabrication to a fixed value. The fabricated circuit includes a feedback resistance and a gain resistance coupled to an operational amplifier core. The feedback resistance is set to a preset value by setting links coupled to resistors which make up the feedback resistance.
