A 0.12μm CMOS DVB-T tuner

Abstract

A DVB-T tuner is integrated in 0.12 /spl mu/m CMOS. The 16mm/sup 2/ chip integrates a double conversion chain including PLL, VCO, voltage regulators, and ADC. The receiver exhibits a 6.5dB NF, a VCO phase noise of -140dBc/Hz at 1MHz offset at 1.21GHz, and a 14b ADC. It is compatible for integration with a digital demodulator IP.
