Abstract: An electrical device includes an integrated circuit having device circuitry, a passive breakdown protection circuit, and a resistor coupled to or included with the device circuitry. The resistor includes: a polysilicon layer coupled between a first terminal and a second terminal; an epitaxial layer terminal; and a buried layer terminal. The passive breakdown protection circuit is coupled between the second terminal and the epitaxial layer terminal. The passive breakdown protection circuit is also coupled between the epitaxial layer terminal and the buried layer terminal.

Abstract: A system includes a controller area network (CAN) transceiver. The CAN transceiver includes a wake-up circuit having an attenuator circuit coupled to a CAN bus. The wake-up circuit also includes a common-gate amplifier circuit coupled to the attenuator circuit. The wake-up circuit also includes an offset generation circuit coupled to the common-gate amplifier circuit.
