Latest Patents

Makoto Sudo holds a patent for "Bias voltage control circuitry for avalanche photodiode taking account." This invention focuses on circuitry capable of controlling a bias voltage for an avalanche photodiode (APD) in accordance with the temperature slope of the breakdown voltage of the APD. The patent describes a reference voltage generating circuit that sets a voltage implementing an optimal amplification ratio on an output terminal. It generates a reference voltage by considering the temperature slope of the breakdown voltage of the APD. The reference voltage is applied to one input of a voltage comparator, which produces a difference between the reference voltage and a voltage input from the output terminal. This results in a voltage control signal representative of the difference.
