Abstract
A controller area network (CAN) transmitter includes an output stage circuit including a CANH port and a CANL port, and an input stage circuit configured to receive an input signal. The input signal is configured to indicate whether the output stage circuit is to provide dominant or recessive states. The CAN transmitter includes a cascode circuit configured to provide output signals on the output stage circuit to provide dominant or recessive states based on the input signal. The CAN transmitter includes a switch circuit configured to, based upon the input signal, switch the cascode circuit on and off.
