To stop the resistor drawing a lot of power at higher voltages you can use comparators that switch in and out different resistors. --- End quote --- The problem with resistors are that i will get false readings in m current measurement.If it is a constant current source or circuit i can just subtract the current of the constant current source. |
| Simon:
Well you are shoehorning one thing on top of another. If this was designed properly it would not be a problem. The current sense could come after all of the regulation with the feedback being taken from the final output. |
| Arjunan M R:
Okay, i will not worry about the current measurement. Is there any way to constantly sink 1mA to a opamp? |
| Simon:
There probably is but i can't be bothered right now. |
