An automatically temperature-compensated electro-optic circuit. There is disclosed an electro-optic circuit including optical mask, light emitting diodes, and photo transistors coupled with operational amplifier circuitry to provide automatic compensation for variations in parameters of the light emitting diodes and photo transistors due to temperature variations. With the inclusion of the invention in an electro-medical monitor an output signal is thus maintained approximately constant for a given position of optical mask regardless of temperature variations.
