  • Signal differentiation with differential conversion circuit
    Patent number: 7719861
    Abstract: A circuit for transmitting signals includes a transformer having an input side and an output side, the input side having a first end and a second end. A first transistor is coupled to the first end of the transformer, the first transistor being configured to provide a first signal to the first end in response to an input signal transitioning to a first state. A second transistor is coupled to the second end of the transformer; the second transistor being configured to provide a second signal to the second end in response to the input signal transitioning to a second state. The output side is configured to output differential signals according to the first and second signals applied to the transformer.
    Type: Grant
