Abstract

This paper presents a tunable low-noise amplifier (LNA) for digital TV (ISDB-T) applications. To receive all channels from 470MHz to 770MHz and to relax distortion characteristics of following circuit blocks such as an RF variable-gain amplifier and a mixer, tunable techniques for LNAs are required. A novel output matching configuration for tunable LNAs is proposed, and an input matching technique is also described. A tunable LNA using the proposed tunable techniques is fabricated using 90nm CMOS technology. Measured results show the proposed techniques are suitable for the LNAs for the ISDB-T.

用于数字电视应用的可调谐低噪声放大器

提出了一种用于数字电视(ISDB-T)的可调谐低噪声放大器(LNA)。为了接收从470MHz到770MHz的所有信道，并放松以下电路块(如RF变增益放大器和混频器)的失真特性，需要lna的可调谐技术。提出了一种新的可调LNAs输出匹配结构，并描述了一种输入匹配技术。利用所提出的可调谐技术，利用90nm CMOS技术制备了一个可调谐LNA。实测结果表明，所提技术适用于ISDB-T的LNAs。
