Abstract :
A mixed-mode QPSK demodulator for home networking application is demonstrated. The target application is high-bandwidth data transmission through the CATV line at home. A prototype chip realised by a 0.18 m CMOS process can demodulate 1 Gbit/s QPSK data with 1.7 GHz carrier frequency in a 20 m CATV line link. It consumes 20.8 mW from an 1.8 V power supply while the area is 170 × 200 μm2.
