摘要： The present invention provides a light-receiving circuit that applies the avalanche photodiode (APD) and reduces the power consumption at a large optical input. The bias controlling circuit of the present invention provides a voltage source, a current detector, a voltage divided, and a controller. The current detector detects the photo current generated by the APD and output the current or voltage signal corresponding to the photo current. The voltage divider divides the output of the voltage source and the current or voltage signal from the current detector thereof may affect the dividing ratio. The controller operates to maintain the output of the divider constant by adjusting the output of the voltage source. Accordingly, the output of the voltage source decreases at the high optical input, thereby reducing the power consumption of the circuit.

摘要： An analog photodiode (PD) module converts light including many AM signals of different frequencies into electric signals. It is desirable to suppress the distortion caused by the non-linearlity of the light-current conversion in the PD module as completely as possible. Extreme convergence of beams enhances the sensitivity but raises the distortion. Prior modules suppressed the distortion at an expense of the sensitivity. The present invention overcomes this problem by positioning the end of the fiber at a point which is closer to the lens than the maximum sensitivity range, thereby providing a distortion that is smaller than the predetermined value. The high sensitivity and the low distortion are compatible at the point.
