I lifted this image off Jung's exciting paper in a 2007 issue published in Audio Express entitled Sources 101: Audio Current Regulator Tests for High Performance.
Q1) Does LED bias matter? Jung proposes about 1.6ma in this example, does decreasing it to 0.6ma change major characteristics of the CCS other than a lower Vf?
Q2) Does a lower bias lead to instablilty?
Q3) Are these characteristics similar, eg. Zo, stability, etc when put in contrast with a ring of two CCS.
Really appreciate any insight.
Cheers!
