Abstract:
A transmitter circuit for a field bus driver includes a first bus terminal and a second bus terminal for connecting a first bus line and, respectively, a second bus line. The transmitter circuit further includes a first supply terminal for receiving a supply voltage and second supply terminal for receiving a reference voltage, a first switching circuit coupled between the first supply terminal and the first bus terminal, and a second switching circuit coupled between the second bus terminal and the second supply terminal. The first switching circuit includes a first transistor and a second transistor, and the second switching circuit includes a third transistor and a fourth transistor. Further, the transmitter circuit comprises control circuitry configured to generate first drive signals for the first transistor and the third transistor and second drive signals for the second transistor and the fourth transistor based on a transmit signal.
