RF Front-end Design of a Digital TV Receiver

D.Sony, Dr.G.V. Mahalakshmi

Volume : VOLUME 2 || Issue : ISSUE 5

Abstract :

This paper presents a RF Front-end of Digital TV Receiver the frequency swept from 100MHz to 1.2GHz in CMOS process. This Front-end is designed by using Inverter with Self bias Current reuse LNA and Mixer which consumes  power  of 14.79 mw from 1.8V supply. The Front-end has good linearity 1dB compression point is       -33.7 dBm, Input-referred third-order intercept point (IIP3) is  -11.54 dBm.It has low Noise figure of 4 dB ,S11 is

-16 dB and high gain .So it is suitable for Digital TV applications

Keywords: self bias, current reuse,1 dB compression point and input-referred third-order intercept point
