A 40-MHz-to-1-GHz Fully Integrated Multistandard Silicon Tuner in 80-nm CMOS

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 external components. It achieves an NF of 2.7 to 4 dB and a maximum gain IIP2/IIP3 of 20/-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 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 2 2.8 mm .

“…Thus, DTV obtain more consideration in the market to try to decrease DTV costs. One of the approaches to reach the goal is to decrease the BOM (Greenberg et al (2013)). A wide VHF/UHF frequency range from 48 MHz to 862 MHz have been utilized by several available cable TV and terrestrial standards like Digital Video Broadcasting (DVB) and Advanced Television System Committee (ATSC) where it can support hundred broadcasting channels.…”
