A triband 65nm CMOS tuner for ATSC mobile DTV SoC

A triband 65nm CMOS tuner is designed and implemented for first ATSC mobile DTV SoC. It supports VHF-I, VHF-III, and UHF bands. The tuner achieves a 2.5/3.0/4.0dB NF at VHF-I, VHF-III and UHF band respectively, while consuming less than 100mW. By using narrowband LNA architecture with input and load...

Description
Summary:A triband 65nm CMOS tuner is designed and implemented for first ATSC mobile DTV SoC. It supports VHF-I, VHF-III, and UHF bands. The tuner achieves a 2.5/3.0/4.0dB NF at VHF-I, VHF-III and UHF band respectively, while consuming less than 100mW. By using narrowband LNA architecture with input and load tuning ability, it can meet linearity requirement for ATSC mobile with small power consumption. It also automatically calibrates baseband low-pass filter cut-off frequency and LNA LC load resonant frequency.
