Abstract
Disclosed is a system comprising a plurality of operational amplifiers, each operational amplifier having individually adjustable operational parameters, and a trimming circuit. The trimming circuit includes successive approximation register (SAR) logic that determines associated memory values. The trimming circuit changes the adjustable operational parameters of each operation amplifier based on the associated memory values.
