ABSTRACT:
An optocoupler system includes a buffer, isolation, and a detector. The system includes a current transfer ratio (CTR) with a temperature coefficient. The buffer includes a light source that generates light that passes through the isolation. A detector receives light that passes through the isolation and generates an output signal based on the received light. A current transfer ratio (CTR) temperature coefficient compensation mechanism is provided that generates a base signal with a temperature coefficient that compensates the temperature coefficient of the CTR.
