  • Apparatus and method for offset drift trimming
    Patent number: 8212606
    Abstract: An apparatus is provided that includes a drift trimming stage that includes a first current source providing a current with a first temperature dependency and a second current source providing a current with a second temperature dependency. The first and the second current source are coupled at a first node and configured to have equal currents at a first temperature. There is further a third current source providing a current with a third temperature dependency and a fourth current source providing a current with a fourth temperature dependency. The third current source and the fourth current source are coupled at a second node and configured to have equal currents at the first temperature. There is a first resistor coupled between the first node and a third node, a second resistor coupled between the second node and the third node. The first node and the second node are coupled to provide a combined voltage drop across the first resistor and the second resistor for reducing the offset drift.
