Abstract :
By making a discrete circuit of a typical op-amp internal circuit, the IC op-amp´s fault modes were investigated. Next, the experiment was performed in six ways to simulate the fault that occurred in the actual IC op-amp and simulation circuit. This paper then proposes a current sensor that has an LED to designate a fault.
