摘要： In a preamplifier for amplifying an input signal supplied to an input terminal to supply an amplified output signal and a reference output signal to an output terminal and a reference output terminal, respectively, a reference level circuit produces a reference level. An amplifier is connected to the reference level circuit and has a predetermined structure. The amplifier amplifies the input signal into the amplified output signal with reference to the reference level to supply the amplified output signal to the output terminal. A dummy circuit is connected to the reference level circuit and has a structure which is identical with the predetermined structure. The dummy circuit responds to the reference level to produce the reference output signal related to the amplified output signal.

The optical receiver comprises a photo diode (340) for transducing the input optical signal into an electrical signal, a plurality of limit amplifier circuits (310-1, 310-2, . . . , and 310-n) which are connected in series which are connected in series to one another and which have offset compensation functions determined by controllable offset compensation time constants, respectively. The plurality of limit amplifier circuits amplify the electrical signal to produce an amplified and controlled electrical signal in dependency upon the offset compensation time constants controlled. The optical receiver further comprises adjusting circuits (320-1, 320-2, . . . , and 320-n) connected to the limit amplifier circuits for adjusting at least one of the offset compensation time constants to make the limit amplifier circuits produce the amplified and controlled electrical signal and an output terminal OUT for producing the amplified and controlled electrical signal as the output electrical signal.
