Claim 13:
14. The system of claim 12, wherein the control circuitry includes:
a transconductance stage with a first transconductance stage input, a second transconductance stage input and a transconductance stage output, the first transconductance stage input configured to receive the output current feedback sense voltage from the indirect current feedback circuit, the second transconductance stage input configured to receive a reference voltage, and the control circuitry configured to vary a resistance between the amplifier output and ground responsive to a difference between the output current feedback sense voltage and the reference voltage; and
a transistor with a first current terminal, a second current terminal, and a control terminal, the second current terminal coupled to ground, the control terminal coupled to the transconductance stage output.
