Claim:
1. A different amplifier device comprising: a first voltage input and a second voltage input; an output resistor; a first switch comprising a first gate and a first drain and a first source, the first gate being coupled to the first voltage input; a second switch comprising a second gate and a second drain and a second source, the second gate being coupled to the second voltage input, the second drain being coupled to the output resistor; a voltage supply; a feedback circuit comprising a third switch and a fourth switch, the third switch and the fourth switch being coupled to the voltage supply; a bias generator circuit being coupled to the voltage supply and the feedback circuit, the bias generator circuit being configured to provide a bias reference voltage to the feedback circuit; and a current source comprising a fifth switch and a first amplifier, input terminals of the first amplifier being coupled to the second drain and the first voltage input, the output terminal of the first amplifier being coupled to a gate of the fifth switch.
