We have a MOSFET that drives a load. The load has a sense resistor in its current path and its voltage is used to trigger a circuit that can disconnect the load if we detect an over current ...
The schematic above is a very good voltage regulator, excepting the high power dissipation for Q1 (also I'd use an NPN instead of a PNP). Can I replace Q1 and Q2 with a high current n-mosfet and ...
I need to analyze a schematic and I am having trouble with this part: The thing is I don't get at all the utility of the N-channel MOSFET at the output of the op-amp. Could anyone explain the ...
I was looking for a voltage controlled current source see here , and I stumbled upon this circuit with description here : Now I am having difficulty figuring out how this works - I made a model of ...
Here is a circuit that seems to work pretty well for allowing a voltage to control a current of up to maybe two amps. It works on the falstad simulator (the triangle wave voltage input produces an ...
