Broadband control amplifier having a wide control range and comprising a differential amplifier in the negative feedback loop. An auxiliary coupling is provided in the feedback loop having a transfer factor which renders the open loop gain independent of the signal distribution in the differential amplifier. The control amplifier can, for example, be used as an input amplifier in a receiver for optical fibre systems, to compensate for the length and temperature-dependent attenuation of the optical link. |
