Abstract
A current mirror circuit includes a first current mirror transistor, a second current mirror transistor, and a bias circuit. The first current mirror transistor includes a gate and a drain. The second current mirror transistor includes a gate coupled to the gate of the first current mirror transistor. The first current mirror transistor and the second current mirror transistor are low threshold voltage transistors. The bias circuit is coupled to the gate and the drain of the first current mirror transistor. The bias circuit is configured to bias the first current mirror transistor to operate in a saturation mode when a threshold voltage of the first current mirror transistor is a negative voltage.
