Abstract:
A bidirectional data link includes a forward channel transmitter circuit and a forward channel receiver circuit. The forward channel transmitter circuit includes a forward channel driver circuit, and a back channel receiver circuit. The back channel receiver circuit is coupled to the forward channel driver circuit. The back channel receiver circuit includes a summation circuit and an active filter circuit. The summation circuit is coupled to the forward channel driver circuit. The active filter circuit is coupled to the summation circuit. The forward channel receiver circuit includes a forward channel receiver, and a back channel driver circuit. The back channel driver circuit is coupled to the forward channel receiver.

Claim (Index 20):
The back channel communication system of  claim 18  wherein:\n the summation circuit comprises:\n a first resistor comprising a first terminal coupled to a first input terminal of the back channel receiver circuit; and \n a second resistor comprising:\n a first terminal coupled to a second input terminal of the back channel receiver circuit; and \n a second terminal coupled to a second terminal of the first resistor; \n \n \n the active filter circuit comprises:\n a first transistor coupled to the summation circuit, wherein the first transistor is controlled by an output signal produced by the summation circuit; \n a second transistor coupled to a reference voltage source, and coupled to the first transistor to form a differential amplifier; \n a first capacitor comprising:\n a first terminal coupled to a first output of the differential amplifier; and \n a second terminal coupled to a second output of the differential amplifier; \n \n a cross-coupled pair coupled to the differential amplifier, the cross-coupled pair comprising:\n a third transistor; and \n a fourth transistor cross-coupled with the third transistor; and \n \n a second capacitor comprising:\n a first terminal coupled to a first output of the cross-coupled pair; and \n a second terminal coupled to a second output of the cross-coupled pair.
