  • Abstract
    A PWM ADSL2+ line driver with 2.2 MHz signal bandwidth is realized in a 3 metal, 2 poly 0.35 mum CMOS process. A low 8.832 MHz switching frequency is used with filtering in the feedback path to suppress aliasing. Signal processing and triangular wave generation are combined in the forward integrators. The driver delivers 100 mW to a 100 Omega line with an MTPR less than -52 dB. Active area is 3 mm2.
