ABSTRACT:
A transimpedance amplifier for an optical receiver includes an integrator circuit for receiving a current input from a photodetector; an integrator capacitance between the input and output of the integrator circuit; a gain stage responsive to the output of the integrator circuit for providing an output voltage representative of the current input to the integrator circuit; and a feedback resistance connected between the output of the gain stage and the input of the integrator circuit for establishing the nominal gain of and in conjunction with the integrator circuit for setting the nominal bandwidth of the transimpedance amplifier; the gain stage may have a gain greater than unity for increasing the bandwidth by the factor of the gain and the gain stage may include a trimmable resistance for adjusting the gain both below and above unity.
