Using current mirror for current sensing in high current MOSFET applications significantly reduces power loss in current sensing circuit and lowers design cost by replacing expensive high power ...

Last time we looked at Spice models of a current sink. We didn’t look at some of the problems involved with a simple sink, and for many practical applications, they are perfectly adequate. However, ...

The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...
