Abstract
An optically isolated current mirror provides an isolated output signal as a function of an input signal. A first optical isolator generates an isolated control signal as a function of the input signal. An amplifier is connected in a voltage follower configuration which supplies the output signal as a function of the control signal and a feedback signal. A second optical isolator generates the feedback signal as a function of the output signal.
