Abstract :
In this paper, a line driver for HomePlug AV powerline communication system has been described. The proposed line driver includes a damping factor control (DFC) network which suppressed the open loop high frequency peaking effect to improve the stability for the various characteristic impedance of powerline. The line driver was fabricated in TSMC 0.18-μm CMOS technology and occupied 0.195 mm2 active area. When operating with a power line and a coupling unit including a 1:4 turn ratio transformer, the line driver achieves 60 MHz bandwidth and 52.14 dBc in-band MTPR, with 5.15 dBm output signal power and 4.44 peak-to-average ratio (PAR), while 2.5 V supply voltage.
