Abstract

See full text

A receiver for a LAN which uses a transformer for isolation. Base line wander is prevented by use of a positive feedback path which provides a signal that compensates for low frequency loss through the transformer. The feedback path connects the output of the receiver to the secondary winding of the transformer. The time constant of the transformer and terminating resistor L/R equals the RC time constant in the feedback path.
