How do you measure the VGS and the VDS when you use a very compact layout?

It is very difficult to measure the VGS and VDS. For VGS especially we recommend using isolated optical probes. Depending on the accuracy you are looking for, it is difficult to measure. The best performance is with the optical probes which can measure the VGS of the high side while it is floating up and down in a converter.
