  • Patent number: 7349465
    Abstract: A transceiver system is disclosed for use in a telecommunication system. The transceiver system includes a transmission circuit with a differential transmitter input coupled via a transmitter input stage to a differential input of a transmission amplifier in an embodiment. The transmitter input stage includes a trimmable resistor, one end of which is coupled to a positive transmit input signal, and the other end of which is coupled to a negative transmit input signal. The transceiver system also includes a receiver circuit with a differential receiver output coupled to a differential input of a receiver amplifier, and further includes a transmission line interface circuit coupled to a differential output of said transmission amplifier and to a differential input of said receiver amplifier. In accordance with other embodiments, the receiver amplifier includes an input stage that includes a first plurality of capacitors and a feedback circuit that includes a second plurality of capacitors.

  • Patent number: 7330545
    Abstract: A hybrid matching system is disclosed for use with a transmitter and receiver. The hybrid matching system includes a pair of transmitter output nodes for providing a differential transmitter signal for transmission, a pair of receiver input nodes for receiving a differential received signal, a pair of line terminals to interface with a transmission line. The system also includes a first transformer having a first set of windings and a second set of windings, and a second transformer having a first set of windings and a second set of windings. The first set of windings of the first transformer is coupled to the transmitter output nodes. The second set of windings of the first transformer is coupled to the first set of windings of the second transformer. The second set of windings of the second transformer is coupled to the pair of line terminals.
