A multi-standard mobile digital video receiver in 0.18μm CMOS process

A multi standard direct conversion receiver for digital video broadcast application is presented. This receiver supports MediaFLOtrade, DVB-H and ISDB-T standards. Broadband multi-standard operation is achieved with a reconfigurable LNA, broadband mixer, programmable bandwidth baseband filter, wide tuning range LC VCO with a fully integrated fractional-N synthesizer. A high linearity signal path enables concurrent operation with GSM transmitter. Out of band transmitter (TX) blockers (DCS/IMT, Bluetooth) are attenuated by a novel integrated elliptic low pass filter. The receiver is implemented in 0.18 mum CMOS process. In MediaFLOtrade mode this design achieves a cascaded noise figure (NF) of 2.7 dB and IIP3 of -8.2 dBm in the highest gain mode. In DVB-H mode this design achieves a cascaded noise figure of 2.5 dB and IIP3 of -3.3 dBm in the highest gain mode. The peak power dissipation is 162 mW and 190 mW (@2.1 V) in MediaFLOtrade and DVB-H mode respectively.
