Abstract
A current generator includes an amplifier having a first terminal configured to receive a first voltage, a tunable resistance circuit coupled to an output terminal of the amplifier through a first transistor, a calibration circuit coupled to the tunable resistance circuit, and a second transistor. The second transistor includes a gate terminal coupled to the output terminal of the amplifier and a drain terminal coupled to a load. The calibration circuit is configured to adjust a resistance setting of the tunable resistance circuit.
