Op Amp Current Source. Op amp current source oscillating. Using ref200 and one external op amp.
In this short post let us understand the operational amplifier based constant current source circuit. The op amp in this circuit u1a is in a closed loop because the negative input and output are connected together through q3 and so the op amp will attempt to keep the and. Remember the following rules about the ideal opamp 1.
