  • High linearity voltage-current converter able to compensate for mobility degradation
    Patent number: 7906993
    Abstract: A high linearity voltage-current converter able to compensate for mobility degradation comprises a first constant current source circuit, a first current mirror unit, a second constant current source circuit, a second current mirror unit, a seventh MOS transistor and an eighth MOS transistor. The first current mirror unit is coupled to the first constant current source circuit, and the second current mirror unit is coupled to the second constant current source circuit. The seventh MOS transistor, the first current mirror unit and the second current mirror unit are coupled to each other at a third joint point of a first conducting wire. The eighth MOS transistor is coupled to the seventh MOS transistor. Thereby, the electronic components used in the present invention can operate more efficiently.
