RESUMO

It was developed in this work a circuit for power line data communication - PLC that enable low speed data transmission in a circuit topology that enable a future integration. The built prototype was elaborated with discrete components and exhibits a compatible operation with a typical PLC circuit. The coupling circuits with the mains wires are extensively discussed. The signal to be serially transmitted pass through a level shifter that allows a level and offset adjust of the signal, later being applied to a voltage controlled oscillator - VCO that performs the continuous FSK modulation in a simplified way. Bit Error Rate (BER) measurements were made, and the results presented numerically and graphically. A monolithic integrated circuit for the VCO, part of this system, was projected foreseen a possible future integration. For this task was performed simulation in the ADS circuit simulator and later in the project flow an integrated circuit layout was made using Cadence EDA tools. The chosen design kit comes from AMS foundry, in the technology AMS C-35, and shows the system integration viability in a single integrated circuit
