This paper proposes a novel idea of a particular optical analog signal isolator called YOUTAB. The digital photocoupler NEC-PS2501 constitutes the main structure of this new isolator. In general, the proposed configuration consists of two different parts; one of them transfers the signal and the other establishes a negative feedback to ensure that the output signal has the same features of the input signal. The operation, analysis, and computer simulation results are shown. The simulation results show that this novel proposed analog isolator is linear in a wide range of inputs.
