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.

Abstract: One example includes an reference voltage generator system. The system includes an amplifier configured to generate a reference voltage based on a respective input voltage provided at each of at least one input of the amplifier. The system also includes at least one input transistor that is coupled to the at least one input of the amplifier and is statically-biased to conduct a current to set an amplitude of the respective input voltage provided at each of the at least one input of the amplifier. Each of the at least one input transistor includes an input terminal that is coupled in series with an input resistor.
