Current-mode preamplifiers are provided. In accordance with an embodiment, a current-mode preamplifier includes a transistor, that acts as an input stage for the preamplifier, and a pair of current mirrors. The transistor includes a gate connected to the input of the preamplifier, a source connected to a first voltage supply rail, and a drain. The first current mirror, which is connected to a second voltage supply rail, includes an input connected to the drain of the first transistor, and an output. The second current mirror, which is connected to the first voltage supply rail, includes an input connected to the output of the first current mirror, a first output connected to the input of the preamplifier, and a second output connected to the output of the preamplifier.
