PROBLEM TO BE SOLVED: To simultaneously execute optic/electric conversion and an identifying operation and to enable a high speed operation for an optical input signal. SOLUTION: A resonance tunnel diode 2 as a driver and a resonance tunnel diode 3 as a load are serially connected between a clock supplying terminal 4 and a grounding 6, a photo diode 1 to input an optical data signal is connected in parallel with the resonance tunnel diode 3. Then, an output signal is taken out of a common connection point of the both resonance tunnel diodes 2, 3. |
