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
