Abstract

A fully integrated, multistandard silicon tuner for the 42–1002-MHz band is presented. The tuner utilizes a single RF port for the whole band and requires a minimal number of ex- ternal components. It achieve s a NF of 2.7 to 4 dB and maximum gain IIP2/IIP3 of +20/–13 dBm, re spectively. It combines a tun- able RF filter and a harmonic rejection mixer to reject all har- monic channels by more than 65 dB. A filtering continuous time ΣΔ ADC minimizes baseband proces sing while supporting the ATSC blocking profile. Continuous background digital calibration allows more than 65 dB of image rejection. Various calibration methods are used to guarantee performance over PVT. The tuner consumes less than 450 mW from 1.8/1.0-V ana log/digital supplies and occu- pies an area of 2×2.8 mm².
