  • OPTOELECTRONICS CIRCUIT COLLECTION

    cal detector circuits that require high sensitivity and wide bandwidth. A high reverse bias voltage across the photodiode junction creates avalanche gain, and varying the re verse bias voltage can control this gain. Although some APDs require a bias of a few hundred volts, many InGaAs and Si APDs require only 60V to 80V. The circuit shown in Figure 1 can provide a positive bias voltage of up ...
