Hi @FvM
In powermosfet high side layout, I have to take kelvin connection from the Source pad and the drain pad to the current sense block. Since it is a current sense block, is it used to sense current or voltage? How does Kelvin connection work?
Thanks

Hi @FvM ,
Shouldn't it be primarily from majority carrier injection? For e.g., in the case of powerfets in powerconverter chips, high side powerfet injects holes into the p-substrate which are majority carriers in psub. Likewise, low side powerfet injects electrons into the nwell.
Hi @sutapanaki ,
Lets say, there are 2 branches of pmos current mirrors with a diode w/l size getting a reference current of 1uA. If one branch has 2x pmos with W/l, then the mirrored current here is 2uA.
If the second branch has 2 pmos of w/l in series, then the current here is 0.5uA. Why is...
