Hi
We are performing an experiment where we need a circuit to produce a constant current of 10mA for 30s followed by a sequence of 10 pulses of 5sec duration, each pulse being 400mA. The pulse separation is arbitrary.The pulses are applied to an experimental resistive device, which has a nonlinear time dependent resistance. We expect that the voltage drive needed might be about 100V but the higher we can design, the better. However we expect the voltage drive will be maximum 200V.
Please give me some tips on how to proceed on this problem
Regards
