An S-band frontend receiver for mobile TV in 65nm CMOS

Abstract

This paper presents a frontend receiver for S-band mobile TV applications. The direct conversion receiver covers the 2.635–2.66GHz band using a frequency multiplication scheme to generate the LO. The LNA operates either in a digitally controlled gain mode or in a bypass state. The receiver achieves 96dB of maximum gain with a corresponding NF and out-of-band IIP3 of 2.9dB and −8dBm, respectively. The frontend current consumption is 19mA from 1.2V power supply. The receiver is implemented in a 65nm CMOS process.
