Controller area network with flexible data rate (CAN-FD) has been introduced to support higher data rates for intelligent automotive systems. To achieve a robustness in the electronic functions of electronic systems, CAN-FD transmitters should provide a good symmetry between the differential signaling on the CAN bus radiating a low electromagnetic emission (EME). This paper proposes a new CAN-FD transmitter which achieves good symmetry on the CAN-FD signals. Also, a so-called ``Ping-Pong” driving scheme is introduced. Without using complex circuits and after-calibration process, this method can match accurate turn-on/off timing of the transmitter signals. The proposed CAN-FD transmitter was fabricated using a $0.18\,\mu {\text{m}}$ automotive Bipolar-CMOS-DMOS process. The measurement results show that the proposed CAN-FD transmitter improves the voltage symmetry of the CAN bus at 5 Mbps, achieving a low EME. [ABSTRACT FROM AUTHOR]
