An Integrated DVD_T Tuner

Abstract

A fully CMOS integrated DVB_T RF analog tuner achieving a 6.5 dB noise figure is presented. The tuner is implemented in a 0.12 mum CMOS process and occupies a 16 mm2 area. The receiver is based on a double zero IF conversion and integrates within the receiver chain the frequency synthesizers and two 4 MHz bandwidth 14 bit analog digital converters. The VCO exhibits a -140 dBc phase noise at 1 MHz offset at 1.2 GHz
