A Low Power DVB-T/H Zero-IF Tuner IC Design in 0.25 $mu{hbox {m}}$ BiCMOS Technology for Mobile TV Reception

摘要

This paper describes fully integrated RF IC sub-system of a DVB-T/H receiver intended for Mobile TV reception. The architecture of the RF IC has been designed to be compliant with the category b2 & c of the MBRAIMoBile Radio Access Interface. specification developed for the introduction of TV into existing mobile phone. The coexistence with GSM transceivers has been taken into account to establish the complete link budget from UHF antenna down to the Digital Front-end. A broadband LNA has been designed for an overall IC noise figure of 3.9 dB. The IIP3 is -5 dBm while 25 dBm RF IIP2 has been measured. A 5th order low pass filter has been implemented for adjacent channel suppression. The total power consumption is 150 mW in continuous mode. Thanks to a new broadband synthesizer architecture using a single VCO, the occupied silicon area is 2.2 mm2 in a 0.25 mum BiCMOS technology
