Abstract: Some aspects of the disclosure provide for a circuit. In an example, the circuit includes an amplifier, a first transistor network, a second transistor network, a first resistor, a second resistor, and a third resistor. The amplifier has first and second inputs and first, second, third, and fourth outputs. The first transistor network is coupled to the first output of the amplifier and the second output of the amplifier. The second transistor network is coupled to the third output of the amplifier and the fourth output of the amplifier. The first resistor is coupled between the first transistor network and the second transistor network. The second resistor is coupled between the first transistor network and the first input of the amplifier. The third resistor is coupled between the second transistor network and the second input of the amplifier.

Abstract: A line driver circuit includes a first input terminal, a second input terminal, a first input stage, a second input stage, a first output stage, and a second output stage. The first input stage includes a first input coupled to the first input terminal, and a second input coupled to the second input terminal. The second input stage includes a first input coupled to the first input terminal, and a second input coupled to the second input terminal. The first output stage includes a first input coupled to a first output terminal of the first input stage and a second input coupled to a first output terminal of the first input stage. A second output stage includes a first input coupled to a second output terminal of the first input stage and a second input coupled to a second output terminal of the first input stage.

Abstract: A wakeup circuit includes an energy detection circuit and a wakeup signal generation circuit coupled to the energy detection circuit. The energy detection circuit is configured to, in response to receiving an input signal, generate a detect signal that is proportional to the input signal. The energy detection circuit is powered by the input signal. The wakeup signal generation circuit is configured to, in response to receiving the detect signal, generate a wakeup signal.
