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 external components. It achieves a NF of 2.7 to 4 dB and maximum gain IIP2/IIP3 of ?13 dBm, respectively. It combines a tunable RF filter and a harmonic rejection mixer to reject all harmonic channels by more than 65 dB. A filtering continuous time ΣΔ ADC minimizes baseband processing 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 analog/digital supplies and occupies an area of 22.8 mm. © 2013 IEEE.
