High-side current sensing using PNP
I have the following three states:
State 1: When system is active with transducers, current through the load is approximately 350 mA.
State 2: When system is activated without transducers, current ...

How is this a current mirror?
This article is talking about floating an IC's GND to use it at a common mode voltage higher than it is rated for. It then says it level shifts the IC's current output to ground by using the Q1-Q2 ...
