A Stepwise Split Power-Driving Scheme With Automatic Slope Control for EMC-Enhanced LIN Transceiver

This paper proposes a split power-driving scheme for electromagnetic interference robust design and its automatic stepwise digital slope control for suppression of spectral emission. This analog–digital hybrid method gives power saving effect up to 24.4%, and also production reliability can be improved by utilizing a failure detection and recovery scheme. For feasibility of the proposed electromagnetic compatibility (EMC) scheme, a Local Interconnect Network transceiver prototype is fabricated in a 0.18-μm BCD process, and experimentally verified to provide EMC-enhanced operation with low-cost and low-power overheads.
