摘要： In an optical receiver, a photodiode converts an optical digital input signal to an electrical signal which is fed into a differential amplifier to produce a pair of true and complementary output signals. The true output signal is received by a peak detector and the output of this peak detector is summed in a first adder with the complementary output of the differential amplifier. The true output of the amplifier is summed in a second adder with a predetermined constant voltage. Difference between the output signals of the first and second adders is detected and compared with a decision threshold to produce an output signal at one of two logical levels depending on whether the difference is higher or lower than the decision threshold. Preferably, a second peak detector having a substantially similar operating characteristic to that of the first peak detector is connected between the source of the predetermined constant voltage and the second adder.

摘要： An optical receiver array includes a plurality of light-receiving elements, a plurality of amplifiers, and a plurality of low-pass filters. The light-receiving elements convert optical signals of a plurality of channels into electrical signals, respectively. The amplifiers amplify the electrical signals output from the light-receiving elements and output the electrical signals. Each amplifier has positive and negative power supply terminals to which power is supplied. Each low-pass filter is connected between the positive power supply terminal of a corresponding amplifier and a first external power supply terminal or between the negative power supply terminal of a corresponding amplifier and a second external power supply terminal. Each light-receiving element is connected between the positive power supply terminal and an input terminal of a corresponding amplifier or between the input terminal and the negative power supply terminal of a corresponding amplifier.

摘要： In an optical receiver, an offset cancelling amplifier comprises a limiting amplifier for amplifying an input signal while preventing amplified amplitude from exceeding a predetermined level to provide an output signal, an offset detector for detecting an offset in the output signal to produce a detection signal representative of the offset amount detected, and an offset controller coupled in the input circuit of the limiting amplifier and the offset detector for controlling an input voltage of the limiting amplifier in response to the detection signal to reduce the offset in the output signal. In order to widen the dynamic range and lower the low-frequency cutoff of the offset cancelling amplifier, the offset detector comprises a Miller integrator.
