Abstract
Current mirror devices and methods for operating a current mirror device. The current mirror device includes a first transistor having a gate, a source, a drain, and a back gate. The drain and the gate of the first transistor are coupled to an input node of the current mirror device. The current mirror device further includes a second transistor having a gate, a source, a drain, and a back gate. The drain of the second transistor is coupled to an output node of the current mirror device, and the gate of the second transistor is coupled to the gate of the first transistor and to the input node. A voltage source supplies a bias voltage to the back gate of the first transistor that adjusts a threshold voltage of the first transistor and to the back gate of the second transistor that adjusts a threshold voltage of the second transistor.
