A wide band Class-D line driver for wireline communications is presented in a low voltage CMOS technology. The new driver improves switching frequencies by a factor of six compared to other works. To reach wide bandwidths, a new NMOS only output stage and a new transconductor are developed. Simulated results of the complete line driver implemented in 0.13µm CMOS, with a 30MHz HomePlug AV input signal and 160MHz switching frequency, show an efficiency of 22.8% with 111mW injected power.
