WebThe Zener forms an inexpensive “floating” shunt-regulated supply for the first op amp. The N-MOSFET drain delivers a metered current into the virtual ground of the second stage, configured as a transimpedance amplifier (TIA). The second op amp is powered from a positive supply and furnishes a positive output voltage for increasing load current. WebIf shunt resistor is 0.1 Ohms (very common) and the current is 1A, this will result in 1 x 0.1 = 0.1v across shunt resistor, this will mean 0.1v output of the differential amplifier when unity gain is used, so it is 0.1v per 1 A. While using a gain of 10 will mean 1v per 1A which is a lot easy and practical.
