<p>Broadband control amplifier having a wide control range and comprising a differential amplifier in the negative feedback loop. Measures have been taken to render the open loop again 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.</p> |
