I have built current sink according to Dave's video. Powered by LM317, OPamp I used is LM6132. I am getting stable oscillation around 375kHz (nice sine oscillation) right from start. When I am increasing the sinking current the oscillation amplitude is also increasing. It gets up around 0.6Vrms for approx. 1A sinking current. Now, I have modified the circuit by adding 2 resistors and one cap according to video #304 ( based on sleepyrobot schematic). The behavior improved a bit. There is no oscillation up to 360mA, then, from that point, when I keep increasing the current it starts oscillate like crazy again, this time on 570kHz. What should I do to stop this oscillation on full scale current sink (around 2A).??
