VISIBLE LIGHT RECEIVER CIRCUIT

摘要

Disclosed is a visible light receiver circuit minimally affected by ambient light, and having a simple structure and low noise. The visible light receiver circuit is provided with a photoelectric conversion unit (10). The photoelectric conversion unit (10) is provided with: a photodiode (11) the cathode side of which is connected to a power source (Vcc); a resistor (12) connected in series to the anode side of said photodiode (11); and a nonlinear resistor circuit connected in parallel to said resistor (12). The nonlinear resistor circuit includes a series circuit comprising, for example, a Zener diode (14) and a resistor (15).
