Claim 14:
15. A circuit comprising:
a knee code selector circuit having a first bias current input, a second current bias input, knee code inputs, and first and second knee point current outputs, the first bias current input adapted to be coupled to a first current source and the second bias current input adapted to be coupled to a second current source, the knee code inputs are coupled to a respective output of a respective knee code storage circuit or register;
an output circuit having a first current bias input, a second current bias input, and a current output, the first current bias input of the output circuit coupled to the first knee point current output, the second current bias input of the output circuit coupled to the second knee point current output; and
a trim digital to analog converter (DAC) having a trim input, the trim input coupled to the current output of the output circuit.
