i test the below circuit using with LM358. and i use instead of n-MOSFET i use CL100 transistor and for p-MOSFET i use CK100.
in my 4-20mA converter circuit for 1.1 v input i get 31mA and for 4.4v i get 45mA as a output. this kind of situation what to do? to get a 4-20mA for my input... is that any components need to change
