After reading about constant current sources, I defined the four cases shown in the pdf. Current should go up to 250 mA.
Implementing B and C with the attached circuit (and its counterpart) is straightforward, but I am not sure how to proceed for A and D. I cannot have Rsense referred to ground anymore.
How could I go away with no fancy ICs?
Gracias for any help.
