摘要

本文介绍了一种适用于调频无线电接收机的60纳米标准射频工艺的低噪声放大器。为了使PCB成本最小化,LNA被设计成不使用匹配网络,这意味着输入阻抗与天线阻抗一致。LNA的总增益为27db,在FM-Radio带宽下以1db步进可编程。LNA的噪声系数为2db, P1dB为- 27dbm,电流消耗为3mA。

A 1.5-V Power Supply inductorless Low Noise Amplifier with 1dB-STEP programmable gain for FM-Radio receivers
In this paper a Low Noise Amplifier suitable for usage in FM-Radio receivers in a standard 60 nm RF process is presented. The LNA is designed to be used without a matching network in order to minimize the PCB cost, which means that the input impedance is in accordance with the antenna impedance. The LNA has a total gain of 27 dB, programmable in 1 dB-step, in the FM-Radio bandwidth. The noise figure of the LNA is 2 dB, its P1dB is −27 dBm and the current consumption is 3mA.
