Abstract
An integrated circuit (IC) chip can include an operational amplifier with adjustable operational parameters. The IC chip can also include a trimming module configured to measure an output voltage of the operational amplifier in response to at least one of detecting that the operational amplifier has a positive supply voltage set to a level greater than a predetermined level and detecting a given common mode voltage at inverting and non-inverting inputs of the operational amplifier. The trimming module can also be configured to adjust the operational parameters of the operational amplifier based on the output voltage to trim the operational amplifier.
