Abstract
A Controller Area Network (CAN) transmitter, in which transitions between output levels are smoothed through use of multiple Digital to Analog Converters (DACs) switched by a multi-phase clock signal. Example embodiments include a CAN transmitter () comprising: an oscillator () configured to generate a clock signal having n equally spaced phases (clk_0, clk_120, clk_240), where n is an integer greater than 1; n Digital to Analog Converters, DACs (-), each DAC having an input connected to one of the n phases of the clock signal and to a common data input line, each DAC being configured to provide an output signal that transitions between first and second output levels in M discrete steps upon being triggered by a transition of a signal on the data input line synchronized with the one of the n phases of the clock signal; and an output amplifier stage () configured to provide a differential CAN output signal from a combination of output signals from each of the n DACs (-).
