Abstract
A transmitter circuit with ringing suppression applicable to a controller area network bus is provided, which includes a CAN bus driver stage receiving a transmit data signal and generating a CAN high voltage signal and a CAN low voltage signal, a first operational transconductance amplifier electrically connected with the CAN bus driver stage for receiving the CAN high voltage signal, and a second operational transconductance amplifier electrically connected with the CAN bus driver stage for receiving the CAN low voltage signal. A common mode voltage of a dominant state as well as a control signal are applied such that when the control signal is logically high, the first and second operational transconductance amplifiers actively pulls the CAN high voltage signal and the CAN low voltage signal to be equal to the common mode voltage of the dominant state so as to suppress ringing phenomenon occurring in the CAN bus.
