Hi all,

I am working on a few current sensors which will be used in a typical DC-DC power converters. However, all the material that i have got are measuring currents greater than 1A and i have to sense the currents as low as 10mA.

There are some issues with the circuit that i am working on rite now  like MC sims are failing.

Hence, i just want to know are there any circuit topologies which can work down to 10mA range across PVT, MC etc..

if anybody worked on them, please point me to get some design material.


Thanks...

Regards,
Anil Reddy
