An optoelectronic receiver having a variable transfer function to compensate
for
operational condition change. The receiver comprises a linear circuit having a
tunable filter. A control circuit provides a signal to the tunable filter. The
control circuit is connected to one or more sensors which sense one or more operational
conditions. The control circuit signal is a function of the one or more sensed
operational conditions. The control signal is input to the tunable filter which
adjusts the linear circuit's transfer function based on the control signal. Further
disclosed are an integrated circuit and optical communication system having the
inventive optoelectronic receiver. A method for adjusting an optoelectronic signal
in a receiver is also disclosed.
