Visible light receiver circuit
Abstract:
A visible light receiver circuit, which reduces the influence of ambient light, has a simple configuration, and generates low noise, is provided. The visible light receiver circuit includes a photoelectric conversion unit. The photoelectric conversion unit includes a photodiode having a cathode connected to a power source, a resistor connected in series to an anode of the photodiode, and a nonlinear resistive circuit connected in parallel to the resistor. The nonlinear resistive circuit includes, for example, a series circuit including a Zener diode and a resistor.
