Abstract: In an example, a CAN transceiver includes a first transistor having a control terminal, having a drain coupled to a voltage supply terminal, and having a source. The CAN transceiver includes a second transistor having a drain coupled to a control terminal of the first transistor, a source coupled to the source of the first transistor, and a control terminal. The CAN transceiver includes a bias circuit coupled to the control terminal of the second transistor, the second transistor configured to convert the first transistor to a diode configuration responsive to detecting high voltage noise.

Abstract: An integrated circuit (IC) includes: first and second transistors having a respective first terminal, a respective second terminal, and a respective control terminal; and cascode circuitry having a first terminal, a second terminal, a third terminal, a fourth terminal, a fifth terminal, and a sixth terminal. The first terminal of the cascode circuitry is coupled to the control terminal of the first transistor. The second terminal of the cascode circuitry is coupled to the control terminal of the second transistor. The third terminal of the cascode circuitry is coupled to the second terminal of the first transistor. The fourth terminal of the cascode circuitry is coupled to the second terminal of the second transistor. The IC also includes dynamic biasing circuitry having a first terminal and a second terminal. The first terminal of the dynamic biasing circuitry is coupled to the first terminals of the first and second transistors.
