| 主权项 | 1. An optical detector circuit comprising: a photodetector including an optical input, the photodetector configured for generating a detection signal; a pre-amplifier including a pre-amplifier input coupled to the photodetector and a pre-amplifier output, the pre-amplifier configured for amplifying the detection signal and generating a low-noise, pre-amplified signal; an amplifier including an amplifier input and an amplifier output for generating an output signal, the amplifier input coupled to the pre-amplifier output; and a bias voltage source coupled in parallel to the optical input and to the pre-amplifier input. | ||
