Description
Summary:We propose a power line communication (PLC) system for transmitting control signals in vehicle through internal power lines, such that the internal wires can be reduced and the vehicles can be lighter. The signals from different devices are multiplexed and modulated to the power lines by the transmitter. In the receiver, first the noise within power lines are filtered. Afterwards the multiplexed signals are selectively extracted by specific codes which are minimally correlated. Finally the control signals are restored from the error-control coded bits which make the information more robust. The maximum data rate of the chip is 50 kbps, and the die area is 3.74 mm 2 using a TSMC 0.18 μm standard cell library with power consumption 22.49 mW.
