Abstract
A driver circuit suitable for outputting a signal onto an output line affected by conducted EMI, has a slope control circuit and an output circuit, (op-amp, Mo, Mto M). It can be used for driving a LIN network. The slope control circuit outputs a slope controlled version of the input signal to the output circuit, which (M,M) is arranged to reduce an amount of conducted EMI induced DC shift in the output circuit. This can involve clipping a feedback signal, and regulating an output stage of the op-amp to prevent the DC shift. Having a separate output circuit can help shield the slope control circuit from the EMI on the output line.
