An internally, resistively, sensed Darlington amplifier includes a Darlington amplifier, at least an input transistor, an output transistor, a resistive divider, a signal input node, and a signal output node. The Darlington amplifier is responsive to an input signal and configured to generate an output signal. An internal bias setting resistor is coupled between the signal output node, a collector of the output transistor, and the resistive divider. The bias setting resistor is configured to set and regulate the bias current of the Darlington amplifier.
