Abstract
A voltage-to-current converter providing an output current with compensation for process-voltage-temperature (PVT) variations of a component in the voltage-to-current converter. The voltage-to-current converter includes a first voltage-to-current converter branch, a second voltage-to-current converter branch, and a compensation current path. The first voltage-to-current converter provides a first current to the output of the voltage-to-current converter based on a variable control voltage. The second voltage-to-current converter branch provides a second current based on a fixed voltage. The compensation current path provides a compensation current from the second voltage-to-current branch to the first voltage-to-current converter branch compensating variations in the first current caused by the PVT variations of the component in the first voltage-to-current converter branch.
