A differential circuit with a function to compensate unevenness observed in the differential gain thereof is disclosed. The differential circuit provides a low-pass filter in one of the paired transistors not receiving the input signal in addition to another low-pass filter that provides an average of output signals as a reference level of the differential circuit. The cut-off frequency of the filter is preferably set to be equal to the transition frequency at which the self-heating effect explicitly influences the trans-conductance of the transistor.

A front end module for an optical receiver is disclosed. The module includes a PD, a trans-impedance amplifier (TIA), an insulating carrier for mounting the PD, and a conductive base for mounting the carrier. The carrier provides first and second metal films thereon. The first metal film carries a photocurrent from the PD to the TIA, while, the second metal film carries the bias supply to the PD. The PD is mounted on the first and second metal films by the flip-chip arrangement. The second metal film surrounds the first metal film to suppress resonances appeared in the trans-impedance spectrum of the front end module.

Front end module for optical receiver

A trans-impedance amplifier (TIA) for an optical receiver is disclosed, in which the TIA enhances the dynamic range thereof but suppresses the variation of the input impedance thereof. The TIA enhances the dynamic range by subtracting from the photocurrent input therein, which varies the input impedance. The TIA also provides the variable gain amplifier with a feedback resistor. The variable gain of the amplifier compensates the variation of the input impedance due to the current subtraction.

A differential amplifier showing a suppressed output offset is disclosed. The differential amplifier includes a pair of differential transistors, a pair of cascode transistors, and a reference generator. One of differential transistors receives an AC signal, while, the other of differential transistors receives an average voltage of the AC signal. The reference generator receives the average voltage of the AC signal and outputs a bias commonly provided to the cascode transistor. The bias is raised by a substantially constant level from the average voltage, which compensates the output offset of the differential amplifier.
